The man outside my building

There's a man that lives outside my building.
Or maybe he lives in the makeshift house outside my building.
He has no legs.
I've lived here for four months and never saw him.
Until last week.
He sits on the side of the road and "walks" with his hands.
He just sits there.
He doesn't beg.
He just passes by and one cannot help but notice.
I almost cannot look at him.
I don't want to deal with how it makes me feel.
That's how selfish I am.
It hurts.
What do I do?
Does anyone take care of him?
I should.
