Also, as Klaas said, you have to show you are a made man. Not by bragging or acting "cool", but you have to stand on your point of view and don't adjust it to the likes of the girl. If her point of view is totally different from yours, and you notice that this may be an issue, then rather don't go for her instead of adjusting your point of view. You will lose respect and all that. However, debating and argueing with someone can be the greatest thing sometimes. That's why we practise it here in the forums. So long as it is constructive and "intelligent" it can make great fun and sure brings you two together.
