I'm thinking of ditching a person with a mental disability on the bus
Why do this to someone with mental disability?
They are such a handful to deal with. I just want to get away from them.
Don't do that. People need assistance, especially those with mental issues. Get help if dealing with them become an issue for you.
Dude my company is ditching them too and I don't want to stand out.
Just because the crowd is all doing one thing, doesn't mean you have to follow suit. What they are doing is wrong, and everyone deserves help no matter who they are. Wouldn't you want to get to know this person, they could be very lovely and you can learn about his perspective of the world!
