Okay, so you want more things to talk about. Here's some quick stories/suggestions. When I was in university, I'd eat lunch with the social group I was pretty much stuck with and on most days, they would annoy the bleep out of me by talking incessantly about the sitcoms on TV the previous night. Apparently they all left their TV stuck on NBC or CBS for two straight hours and not only sucked up every bad joke but felt the need to spend 45 minutes the next day rehashing everyone of them. Now what you aren't supposed to get out of this story is that I was bored with it, you're supposed to get that 10 to 15 people (half female) really enjoyed doing this. To me people are much more boring than you'd ever think... but let me try to put this into positive terms... people are really into pop-culture so if you just watch one sitcom a week, a new big blockbuster movie once a week and go to the occasional concert you'll have plenty to talk about. Concerts are great because not only do way more women than men attend most of them but they sell tickets in such a stupid manner its an hour conversation alone on how you got your ticket. Plus by the clever marketing strategies of the music industry, by definition you're "cool" to have seen some big star in person.... and chicks are even dumber than men to believe this. So when you tell them that you managed to wiggle out a prime seat to see so and so they can't help but be impressed that you got so close to so and so.
Now, of course, from a christian perspective, I'm not telling you you have to embrace the many evils of pop-culture, I'm just telling you things that will give you commonality with women.
