So, it’s not just a guy thing to be funny. It can be either way. If you’re laughing at her jokes, she’s funny. As simple as that. And be sure to let her know that once a while. I’m sure she tells you how funny you are when she laughs mindlessly at your jokes!
You can also go on a roll of you’re sexy, you’re beautiful, you’re so hot or you’re a good driver or a good cook but the above mentioned compliments are a bit more unconventional and are rarely said out loud. So whenever you do get a chance, say them out loud and make her feel special. What say?
