Hi guys, I recently got invited from a girl whom I met at a bar. We had a pleasant night, but only kissing and some touching. Later she said she would like to invite me to her birthday party next week at her place, and I said I would love to.

But now I'm getting nervous because I tend to be very shy in front of a bunch of strangers. So far I only know how to interact with one person, when it comes to more than one and big group conversation my mind just go blank. And I think it will be awkward to let her find out my inconsistency at the party.

So any good advice regarding staying cool and avoiding awkward? And what should I expect from a stranger's birthday party? I actually never been to a birthday party before, so I wonder what kind of activity do people do at a birthday party. Any comments will be appreciated.
