It's very hard to tell sometimes. I dont have people over my place because its basically boring. My friend, however, has people at his house basically at all hours every day. That's because he has bomb buds, smokes out just about anyone who comes by just out politeness, has a Wii, xbox 360, PS2, dope surround sound, and what not. I'll spend 12 hours there and he doesnt seem to mind, I think he gets lonely sometimes. But yeah, sometimes I dunno if I should leave because he doesn't make much of a show of letting you know. I think a lot of people do that because they dont wanna seem rude.
