So my sister is dating a Marine (is that capitalized? I kinda think so, but I have no idea.) Because I have zero military experience, I feel like I never have anything to talk to her about. And I don't understand half of the terminology she uses. That's just part of the problem, though.
I don't particularly like the guy so I've never had time to bond with him (he also lives in a different state than me.) But I feel like my sister is simply hanging out with his family and ignoring ours. Last week, none of us heard from her for an entire week.
I just want my sister back, but I feel like I'm making this guy out to be a bad guy because he's a Marine and that seems a tad bit anti-American to me (which um, is not the case.)
Any advice just on like...how to relate? Or how to understand? I survived a long distance relationship, so I get that aspect of it - but I'd never put my life on hold for anyone else, and that's what I feel like she's doing. So it's hard for me to be nice, basically. It feels like all our convos are about nothing

It seems so trivial now that it's in writing, but I'd appreciate advice anyway.
I guess, to tell you the truth, I've never had much of a desire to grow facial hair. I think I've managed to play quarterback just fine without a mustache. - Peyton
