6th March 2008. Advice needed. Boyfriend or friends?

Right, ugh.
This Saturday I was gonna go to Cardiff. I mean nothing special I go there every weekend. Just hanging out with my friends as I missed last Saturday because I had to get a prom dress.

But then my boyfriend invited me camping with him and his friends Friday night...into saturday morning. Which meant I would miss going to Cardiff.

But when I asked my mam if I could go camping she said no. its "too cold." But basically I think she just doesn't want me sharing a tent with him.

What would you have done?
I don't know whether to start begging my mam harder or just have a good day out with the girls.
