A lot of people say men who can't make a woman laugh are out of the race. I don't think I'm not sociable or introverted, not always anyway, but my personality is not bubbly. I'm a quite serious guy. Jokes just don't come naturally to me. I often can laugh at people's jokes and followup on one, but cracking one on the spot or one on one with girl is jus not me. What can I do about this? People say you can't really change your personality or be someone else. Am I done for?
