It's not about forcing him to drink, it's about presenting him with the temptation. But, hey, just keep going with the whole "real men pretend they don't have problems" bullshit, by all means. You worry about him enough to play watchdog the whole time, but not enough to try and avoid the situation in the first place by just goddamn saying something so I don't inadvertently create a hostile environment.

I don't know what your Sam does back home, but I'm a counselor at the VA. And addiction isn't my specialty, but I sure as hell see it often enough that even accidentally fucking with someone who's recovering makes me feel like a goddamn asshole. And I'm talking to you about it because you've apparently decided you're responsible for him, and like hell I'm going to force him to talk about it, because that's just a bad idea on so many different levels.
