P bum
A park bum is someone who used to have friends but now just sits in the park and stares at pigeons like they owe him money.
That park bum threw a sandwich at a pigeon and it ran away.
I asked the park bum why he was there and he said, 'I ran out of places to be sad.'
The park bum tried to talk to me and I said, 'You’re not worth my time.'
