My cousin is currently deployed in Afghanistan. I'm planning on sending him a save-the-date because he's my family and everyone else is getting one. I'm worried about coming off like a self-centered brat though. I'm worried it's going to come across like: "Hey cuz I know you're probably busy with that whole war thing.. but I'm getting MARRRIIIEEEED," which is not what I want.
I wouldn't just send the STD, I'd include a note with it. He's not currently in a relationship so I can't send it to his SO instead.
