This is probably me a bit.
I don't find the minutia of peoples lives interesting. Holidays, kids, what X said about Y, who you bumped into last week. It puts me to sleep. And I'm not saying other peoples lives are boring, I'm equally uninterested in talking about my own life as well, and I certainly don't find that boring.
I'm much more interested in having a conversation about something specific. Politics, sport, films, history, science, whether you wash your legs or not in the shower (one that came up in work the other day).
Luckily I've found a friend group that are all pretty similar. We do the "How are the kids", "Going anywhere nice" bit, but its out of a sense of social nicety. We get it out of the way in the first 5 minutes and then spend the next 4 hours talking bollocks.
DP is very different to me, and likes to talk about her day at length. And I listen, because its important to her and I love her, but then she asks me how work was and I say "Yeah fine" and then start banging on about some obscure bit of history I heard about in a podcast this morning. And she listens because its important to me and she loves me.
The exception to all of the above is problems. Me and my friends will all happily support each other if somethings wrong. My best friend has been going through a horrible divorce and custody battle over the past year, and so we've all been there for her. Sometimes that means listening to her vent, sometimes that means trying to problem solve an issue, and sometimes that means taking her mind off it and talking about Star Trek.
