Anyone who thinks that a 19/20 year old can't get easily excited about little things and say things like "Oooooh, I want to squeeze them until they pop!" and clap their hands like a little kid clearly has not met my girlfriend when she's in a happy mood.

EDIT: And now that I think about it, I can think of a few others I know that are like that, too, including people from this forum. Hell, on occasion, even I can be like that - where's the fun in being serious all the time? But, for what it's worth, when Danielle does those weird things I do look at her like she's lost the plot. Or I just laugh. xD
