I'm going for a meal at a restaurant with one of DP's school friends and his wife later. I've met DPs friend a few times and he's a nice guy, but never met his wife. I'm looking forward to it, but I'm not very confident meeting DPs friends' wifes/girlfriends like this - DP and friend will be discussing the World Cup all night and old school days, while it's assumed I'll 'make friends' with the wife.
But I never know what to say and afraid of awkward silences. I'm quite introverted and don't tend to talk about myself much. I also hate conversation drifting heavily onto house prices and other mundane/depressing things. So any tips for being sat with someone I don't know at for 2+ hours? What do you talk about with people you're with in these kinds of situations?
