History is shaped by our hands.

I just got back from my gf's house. I watched the Packer game with her and played Trivial Pursuit with her family. We also took her dog for a walk.
It was fun, but its always weird when I'm with her and her family. Allow me to explain.
On Friday night just the two of us went out to dinner and then back to my place to watch a movie. It was perfect. When we are alone, I'm her boyfriend.
However, when I'm with her family, I could be anyone. I just kind of blend into the surroundings when I'm with her family. Part of me thinks this is good, because she AND her family are really comfortable around me. Another part of me just feels kind of blah about it. Not like I spent an afternoon with my girlfriend, but like I spent an afternoon with my family.
I still get all giddy with butterflies in my stomach just when I feel her prescence next to me... and while I feel that from her when its just the two of us, its totally gone when we are with her family. Its like she hides those feelings away when they are around.
I'm probably just overreacting. I should be happy that I'm already like a member of her family and we haven't even been dating for 2 months. I should also be happy that even though its been almost 2 months, her smile and her touch still makes me weak like it did the day we met.
