Now, wait a minute, you young whippersnappers!
First of all, I would never judge someone for parking in a handicap space. How could I possibly know what your illness is or in what way you are incapacitated? It's the same thing with people who ride the carts in the stores-I would not dream of questioning them. I'm the one who always tries to help by getting things for them they can't reach, etc, and I am always rewarded with a smile.
I don't think it's just about age. I believe people who are rude and impatient and bitter and mean spirited in their later years have probably always been that way. I've also been the victim of agism. My left knee doesn't work all that well and I have to use a cane to walk any distance. Most people are decent about it and go out of their way to wait when I'm crossing the cross walk, or pull a shopping cart out for me. The bus drivers are either patient and nice or they are crabby and impatient if I have trouble getting on the bus. Some people will hold out their hand and some will look right through me as if I'm invisable.
I'm so sorry that you have had negative experiences with people who are older. I am sorry you must face such a debilitating illness. But please don't think that when someone is rude, it is just about their age. No one, young or older, has the right to question anyone about their health. But some people were raised with manners and to have respect for everyone-and some weren't.
And some older people do use their age to gain an advantage over other's.
I just think being 62 is cool because I get discounts! And honestly, the next time some old bat questions you, just tell her to fork off. I would.
