Take things more seriously. Jokes are fun and nice, but I think it might come off as you just feeling comfortable with them, but with not much more. If you wish to be with them, then you may proceed. If not, then that's a whole other thing to deal with. This is something that, in the case you want to be with her, you should take some time to think about. Pay attention to the little things, and by that, I mean that maybe there are small gestures that suggest you feel comfortable with her or vice versa, and maybe even suggest you are serious about a relationship.
But, by the looks of it, I kinda have my doubts. From my perspective, i'd imagine this is probably her just being playful. You'll need some time to figure out if she actually likes you, and see if maybe that's just a way for her to show her feelings.
Hope that helps.
Help me know why I cant seem to do anything useful. It's irritating the fuck out of me and I'll hear something like "Wow! You're so talented, you could be capable of even becoming a famous artist/musician!", and then I think about the word "capability", as I take note of how little I do. I don't do anything. I want to do something, and I rarely, if ever, do so.
Woops here's what I meant to say: "just respond with 'do it'."
