Disabled - Look after your bloody self!

My faith in the world had just been shattered.
Walking home from the town I saw a girl in a wheelchair, going in the same direction as me. Having spent much of my life trying to do right and help people I could see that she was having a hard time, struggling to push herself up the road and looked like she might appreciate some help.

Forgetting that we live in a political correct world corrupted by idiots I said to the girl. " do you want a push?" Big mistake, very big mistake. "F@£* off" was the reply that greeted my offer of help.
Now maybe its me, but would a "No thank you I am quite able to look after myself," "I'm OK" or "no I rather struggle so passing people can feel sorry for me" have done far better.

When the heck did the world changed so that an offer of help is seen as something detrimental or condescending. Where does this stop. Can I ever offer to help anyone again.
I am over 6ft tall so now someone says mind your head as I walk towards a low doorway should I take exception to it and shout abuse, your only saying that because I am tall?

So, let it be know that from now on, struggle, suffer, fall, hurt and cry in pain, and don't expect any help from me if your in a wheelchair.
If you would really love some help then blame the girl in the chair tonight when I don't offer, she has really annoyed the hell out of me.
