As a wheelchair user, often I am grabbed unexpectedly by strangers trying to be helpful. This is actively terrifying, imagine if a stranger picked you up against your will. It also risks damage to me and my chair, as often people do not know how to control it while pushing. If someone looks like they need help, ASK FIRST and respect no as an answer. I’m an adult, I know what I’m capable of and don’t need strangers – even well meaning ones – invading my personal space.
