Girl advice please?

ok so I went up to this girl that I saw at a concert the other day. I tend to sometimes sound like a little kid sometimes and it's quite dorky, but a lot of girls tell me that its cute. well I went up to this girl, my friend introduced me and I said "I just thought that you might like to know that you are exceptionally gorgeous". she had a big smile and said "aww thank u" girls what would you think if a guy said this to u?

I would probably say aww thank you too. Girls love to be complimented, especially infront of other people :]

I would also say awww thank you and smile.
I agree with lovemyvarona 100%
it makes them feel beautiful =]
