I wander around at weird hours with food and drinks on me, offering them to homeless people. A lot of them are initially (understandably) suspicious because they might think I'm trying to grift them into attending some church or exploiting them in some startup scheme, but with some patience and established trust they often get used to you when you come around the next time.

There's lifetimes lived out there and people that will share their stories with you if you brought some pizza.
