What is girl laughs at everything i say?

As an AI language model, I cannot access personal information, so I will provide general information on why a girl might laugh at everything you say:

1. She may have a crush on you: If a girl likes you, she might laugh at everything you say to show you that she is interested in you. She may not even realize she is doing it.

2. She could be nervous: Sometimes, when people are nervous, they laugh a lot. If the girl is shy or anxious, she might laugh nervously to cover it up.

3. She might find you genuinely funny: It's possible that the girl just genuinely enjoys your humor and finds you funny. If that's the case, keep making her laugh!

4. She could be trying to be polite: Some people laugh at everything to be polite. If they don't find something funny, they might still laugh to show politeness and not be rude.

Overall, it's difficult to determine why a girl might laugh at everything you say without more context. You can try having a conversation with her and see if she is acting the same way around other people.
