In some cultures, relationships are arranged and the people involved learn to like and love each other. But here it's reversed. We think we know how to love and like someone we just need to learn the person. Now I don't think I'd particularly care for the arranged relationship thing, but I can see how some would think the pros outweighed the cons. The things some people go through to pick up someone is really startling. We buy people drinks, we come up with clever things to say, we put ourselves on the line in hopes that that person will bite plus a ton of other things. It seems like a really complicated set of things we have to do in order to engage in something that's really complicated.
The biggest problem about the whole dance is that there aren't any set rules or processes. Every time you get out on that floor trying to find a partner it's different. A different place, a different person, different words, different everything. All you can do really is pray that you can piece together the right words, looks and gestures from a 100 gallon drum and hope you have the things you need to put together something successful.
Perhaps I'm just bitter about it all because I've never been particularly good at picking up women. I've had a few successes but a whole hell of a lot more failures. I'd be sent back to the minors if my success rate was my batting average. Sometimes I think that little kids got it right. If you like someone, push them down and kick dirt on them. That'd be so much easier.
