Ricechex. In all seriousness, if it really bothers you, become friends with his girlfriend. Then you’ll control ever aspect of him and/or be one responsible for the breakup 🙂
No seriously, do a meet and greet thing with his girlfriend. You don’t need to worry about what to talk about. Somehow women just find ways to talk about anything 🙂
Anyway, meet with his girlfriend, and you know chit chat…And after some time. Do her a favor here and there. And the after some time, just ask her if she can talk to her bf about parking that thing elsewhere. Doesn’t hurt to try. In one case, you’ll might end up gaining a friend. In the worst case, you know you never want to deal with these people.
