Rude and Angry People in the Supermarket

First let me say, I am not always the nicest person in the world to deal with, I get nasty and, well, yes, BITCHY, note the capital letters, at times. I am not perfect, I am not in a glass house throwing the preverbial stone. I just don't understand, how people, in public, can't be more observant, and tolerant.
Last week, I took my mother food shopping. That in itself doesn't seem like a great task, right? Let me digress a little here, my mother, almost 4 years ago was diagnosed with some unknown form of cancer, she had a tumor on her optic nerve, piercing the lining of her brain, on the left side. Ok, if that wasn't enough to deal with, she had to have the rapidly growing tumor removed, which meant a long(something like 13 or 14 hours) operation, removal of both the tumor and the eye, a long recovery, radiation, burns from the radiation, exhaustion, and comming back to almost perfection. She was back to driving, living her life, taking herself back and forth to church, going to the local doctors, going to the food store, etc. Then my brother died, not a great loss for me, but for her, well it was, so that added new stressors to her life. Three months after my brother died, she started experiencing changes in vision, so she went for an eye exam, and needed glasses for the remaining eye. One week later, she drove herself to the vision center to pick up the glasses, they appeared to be the wrong perscription, she called the doctor who ordered the script, no that was correct. Her vision was deteriorating, rapidly, by the monday(she picked up her glasses on friday) she had an emergency opthamology appointment, and didn't feel safe to drive around the corner to it, so I took her. In three weeks she was totally blind in the remaining eye.
Now, a year and some months later, the 2nd opthamologist(a specialist) has finally come right out and said that he thinks the cause is radiation poisioning. She had the radiation treatments so close to the optic nerve that it made her go blind. So that is the background, but she still lives alone, and is doing well, she has lived in the house for 50 + years, so it wouldn't be a great idea to move her to a new environment.
Now, once every couple of weeks, I take her to the food store. I also go over to the house to clean it for her, I go to get her milk, I get her bread, I take her to the doctors, I do her laundry, she doesn't do the basement stairs any longer, I cook meals for my family, and make sure that there is always a plate made for her, so that she has ready made meals for the microwave. So, once every couple of weeks isn't bad to take her to the food store. I am not tooting my own horn here, I feel that it is my responsibility to take care of her, she is after all, my mother, and that is the right thing to do.
So , last week, we go to the food store, Pathmark, to be exact. My daughter, who is almost 4 also accompanies us. I get a cart, put my llittle one in the seat part. Get my mom out of the car, secure her to the handle, put her cane in the basket part. Then I get another cart, for my groceries. I push my cart, and pull her along. We snake up and down the aisles, trying not to block, or bump anyone.
This is the scene, the ladies in the deli dept know us, the cashiers all know us, so the problem, you ask? The other shoppers!
They are MORONS. Do you think I am pulling her cart to be funny?
SHe is wearing an eyepatch over her missing eye for GOD's sake. I say things like "we're moving now mom." I know all of you aren't deaf!
I literally have to tell people that she is blind, can you imagine? They stand behind her, and becasue I haven't moved her to the side fast enough, making those tisking noises! So, one older lady who was looking quite annoyed, and making the noise, I embarrassed, I told her in a very loud voice, so that everyone else in the aisle heard," I am so sorry to be in your way, SHE IS BLIND AND DOESN'T KNOW YOU ARE WAITING FOR HER TO MOVE!" Can you believe that the woman didn't even look embarrassed? She humpfed and went around us. I thought that the older folks were supposed to have more patience? I expect it from my generation and younger, we want everything now, but folks my mom's age?
Then, when we were on line, an oler man was being a BOOB too, watching me make out the check for her groceries as well as mine, and we were inconveniencing him!
I just don't get it, folks, have a little patience, be kind to those around you, you may need their assistance some day!
Sounding off, that is all!
I don't mind when people are rude ot me, well I do, but that is another story, but really, to a blind lady?????
I hope those two people learned something last week, as the old addage goes: There but for the grace of GOD go you or I. You never know what or when something will happen, just a little kindness and understanding go a long way.
