Take It or Leave It
Men sometimes do pull off a "moving" pick-up line, with just a few words like, "Hi! Do you want to go to a party?" and other similarly direct approaches. But we feel you will ruin a lot of good opportunities that way, even if you might be successful sometimes. But it is up to you, the reader, to decide. Maybe you want to try such direct approaches a few times and see how you do. At least it is very simple and easy to do.
We think that the chance of success of a direct approach depends more on the appearance of the man than other approaches. If a girl is very impressed by a man's appearance, she may well go along with it. But if a man is more ordinary looking, she may not. Such a man would do better to build up his case more slowly, in the more conventional way.
