When I approach a woman at a bar, I usually like to have a game plan (along with an escape plan, because it’ll probably end badly. This goes through my head when failing miserably…)
However, sometimes it’s good to just go up and start talking; let your natural charm, wit, and silliness win them over. Let the conversation flow naturally. You’re an intelligent, social being, so just talk about anything. Your brain is your enemy, kill it with alcohol.
Of course, it doesn’t hurt to have a wingman helping you out. A story will be written soon, with a new cavalcade of characters.
Afterthought: I didn’t know this before, but apparently some people just don’t know how to make conversation. As human beings, those people should have the social skills to respond with more than one-word answers. We are people; we are social beings; how hard is it to be a person?
