I do not enjoy business socializing, but it is a necessary part of my job. What I've found is that keeping up on sports helps a lot. Men of all ages can go on and on about sports. Choose a favorite team -- and it does NOT have to be the home team, just have a reason WHY you like the team if it isn't the home team. Be able to discuss the current stats. Did you know that the Cincinnati Reds pitcher pitched a NO HITTER last night?!? I think it was 24 years coming...his name escapes me, somethihng like "Homer." So, for tonight, read the sports page before you go.
Ask or expect: Are you originally from Ohio? People of either gender like to talk about where they're from and like to ask others. A lot of times, you can find common ground in places you've lived or traveled.
Ask or expect: What do you like to do in your spare time? It's fine to mention the kids and then add, "but I also like to ______ when I have time" (read, travel, exercise). People of all ages and genders can share info on favorite books, favorite places to travel, dream places to travel, next trip planned, types of exercise enjoy, which healthclub belong to, fitness goal of a half-marathon/triathalon/improving health.
Old pompous men tend to also like to talk about wine (which tends to bore me a bit). If you know a bit about wine, that's great. If not, just smile and nod.
One thing to keep in mind is that when you walk away from the conversation you should have learned a little bit about them, but they also should have learned a little bit about you, too.
