Sam's dad isn't around very much. As far as we can tell, that's a good thing for Sam and his mom. We're told:
I've got no problem with people getting divorced. If you can't stand someone, then you shouldn't have to be married to them. It's obvious. And I wouldn't have wanted to grow up with my mum and dad arguing all the time. To be honest, I wouldn't have wanted to grow up with my dad full stop. (10.67)
Yikes. We know Sam hangs out with his dad from time to time, but he doesn't pretend to be close to the guy. His dad is always talking trash about Europeans, and he doesn't make much of an effort to be in Sam's life—well, unless you count giving him advice on how to pick up chicks with his baby or illegally buy beer. Great parenting, dude.
