What if she goes? What is she doesn't go? Will it make a difference in what you do or how you act? Have fun is what you do. Be happy, but not hyper-happy. Maybe give her a compliment, but don't cling to her.
And yes, i will have fun regardless.. i was worried about awkwardness... i'll just be myself, the happy guy i am..
if she comes i'll give her a compliment.. if she doesn't .. i'll compliment myself
