I get exactly the same OP and I want to tell them all TO FUCK OFF TO THE OTHER SIDE OF FUCKITTYYY! 
I've had people actually fall over the top of me whilst I was in my wheelchair we were at legoland and the man was over 6ft and a big guy,I could have ended up in hospital seriously ill because of that bloody twat my DH was ready to knock him out!His reason he was looking at his phone,my God if he'd fell on a pram with a tiny baby in he would have crushed them to death he really would!
People stand in front of me so instead of seeing what I was looking at I get to look at strangers arses,great day out that is!Honestly it's like some people see someone in a wheelchair as a meeting point for a fire drill,there will be loads of space everywhere else but not they have to stand right infront of me literally on top of me,I've had people nearly fall onto my laps doing that before,other's have strode on my feet.
I'm already in a wheelchair and fighting to live as long as possible for my 5DC and my DH for fuck sake I don't need ignorant idiots trying to help bump me off any sooner thank you very much!
I get the same with the parking spaces,I'm in a wheelchair and seriously ill and in constant pain as well as being disabled and so far it has always been the older generation that kick off,even those that aren't disabled themselves it's like they're jealous that I have a disability badge.For people like that my DDad and DH tell them it's a bloody disability badge not an OAPS badge haha and my Dad's 80 and disabled.
People that infront of me praising my DH for how well he copes now them I would consider doing time for.It really pisses my DH of as well.
Cheeky fuckers,I became disabled a year after having our 5th DC but I still manage to function and do loads more than I'm supposed to.I'm the one who sorts holidays,days out,celebrations for our 5DC,my family and DH's family,the laundry,bathroom and kitchen,the gardening and I was always the one that did the DIY.
I have never ever treated people the way I get treated,I had friends that had disabilitys when I was growing up,as a child it wouldn't have occured to me to be an arse because someone was disabled why would it?! So God only knows what's wrong with some of these so called adults that so many of us have to deal with!
I've talked about fitting a small camera to my wheelchair to film just what I have to face every time I have to go out of the house,I think maybe now I should and stick it online so people have a bloody clue just how it feels it might just change some attitudes towards those of us that are disabled for the better!
