I can assure you, if you're friendly, the hospitality of others is endless. Particularly of note was Central America -- you could just get off at a bus stop, wander to the nearest cafe and people would be throwing themselves at you to hang out and chat. I had my guard up at first, but after a while it got so normal that it wasn't uncommon to find myself on some random person's couch/floor for a night/week here and there.
