NO GOOD DEED GOES UNPUNISHED!!!!

I am so P.O.'d right now I could effin scream!!!!
OK, so here is the deal, my MIL (think Marie Barone and the mil from the book Vinegar Hill-very whiny & helpless acting) had surgery for a uterine tumor on Friday, complete hysterectomy. This was done by making a gash in her abdomen of about six or eight inches-like a C-Section for those who have had one.
She was released from the hospital on Sunday. For Sunday dinner they had TV dinners. So yesterday I went to Your Secret Chef and picked up a glazed chicken breast with rice dinner for them. Knowing that this would be healthier for them than a sodium laden TV dinner or whatever crap they usually eat. They don't eat healthy at all, and my MIL is diabetic with heart issues and FIL is also a heart patient. A lot of times for dinner my FIL will eat bologna and crackers(and its not a money issue either). YEAH.
So I had the hubs drop off the chicken and rice dish. Well come to find out that my FIL WON'T eat rice. NOT, THANK YOU for thinking of us, but 'Charles won't eat rice'.
I had ordered several meals for them that I was picking up this afternoon, and you guessed two of them had rice and the other had noodles, another food Charles won't eat.
So you know what, I kept the food that I picked up for them. We will eat it ourselves. I am tired to death of bending over backwards for these damn people to have them be so damn hateful to me for 15 damn years!!! This isn't the first time I have been treated this way.
You know when I had my C-section back when my son was born, I would have been thrilled out of my mind if someone had taken the time to think of me and bring us a meal. It was a hard surgery and a long recovery. I could barely walk, so I know she is in the same kind of shape.
I just don't get these people.
Nothing is ever good enough. Why couldn't they just be gracious and say "Thank you"?
