<human>: Can you condense the text into a few key points?

So, I played a gig tonight at a local bar, and it was the first public performance with my new band. I reckon it went pretty well for a first performance, as everyone was really relaxed, great environment and so on. Anyway, we played first, and as I was playing I noticed this girl in the audience. I later realised that she was playing after us, and god was she good. One of those typical singer/songwriter types, but also kind of Celtic. After a few beers(i was still in 100% control), my mate convinced me to go and talk to her, so I did. We got chatting, and we seemed to have a lot in common. Both into music (obviously!). Anyway, just by her looks i could tell she was a lot older than I am, so I asked. turns out she is studying second year uni, which in Aus equates to about 20, give or take a year (she looked younger than 20 to me). Anyhow, I'm currently 17, but 18 as of the 2nd of March, so not too far off. I avoided disclosing my age, and successfully asked her for her number. Now reddit, my question is this. Usually, if we were both a bit older such an age difference wouldn't matter, but considering i am technically 17, it might prove a little bit of a hassle if i try to ask her out to dinner or something. What do you think??
<bot>: = met a girl at a gig, i'm 18 in 3 months and she is around 19-20. (me in school vs her in uni). Too much of an age gap?
