Why isnt Stephen Hawkings going to heaven Because there is no ramp to heaven, only a stairway
I don't get it,  Are you making fun of a disabled person?
It was a joke, so stop being sensitive. We are not able to make fun of disabled people especially about their being disabled like not having mobility. We are just making light about a situation where there is no means for disabled individuals to get around to different sections of the locations.
You failed to notice that Stephen Hawkings achieved a lot more than any able person despite being disabled. It's not right to make fun of physically disabled people, they're as good as any other person.
