Making a girl laugh is a very vital way to make her like you. Laughter is key when it comes to convincing someone you want to be close to. See How to make her laugh:
1. Make her smile: Before making her laugh, make her smile first. Being completely silly and giving hilarious compliments will do the trick here.
2. Relax and laugh too: Making someone laugh is all about what you say. Be relaxed as you say it and be ready to laugh as well.
3. Confidence: Be very confident that you can make her laugh and that will help you sell your humour.
4. Use what is around you: It is called observational comedy.
