You can understand some of the bad feedback, we have an estate across from us viewed from the street the houses are gardens are in a terrible mess and there stand a brand new top of the range mobility car, new cars in the mobility bays the owner put up the badges and walk away and come back with shopping bags with ease.
The general public does not really understand disability, I know I did not until I became disabled, there are those who abuse the system we have all witness and seen it, the downside is bad publicity and resentment towards disabled people.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
