OK, just in case that handwriting is hard to read, here's a transcript:

Hey, Francis,
I got your letter the other week, but I guess I've been struggling with what I can write back? Prison's how you'd expect it, mostly it's a whole lot of nothing. Until it's not. But you get enough "alpha" males in one place, I guess it's always gonna blow up at some point or another. The worst is the food though. Jesus, it makes your skills in the kitchen look gourmet!
There's a couple other of Vince's guys in here with me. They're your typical, empty headed brutes, all fists, no thinking sort, but it's good knowing at least someone in here has my back.
Anyway, enough of that, I'm boring myself. Tell me what else has been going on with you? How's the new job? You feeling any better about the people there? How's the pregnancy going? She's, what, four months in now? You come up with any names yet?
When the little guy's born, you'll have to send a photo over. And tell 'em all about how cool their "Uncle Sammy" is, haha.
Missing you,
S. x
