I don't think guys should get upset when their girlfriends at like this... they should be flattered
It just means that they are comfortable with their boyfriends and they make them hyper and happy. I really don't see a problem with it... but then again, I'm one of those girls, lol so this is a very bias opinion.
But, I know, I do love to see my boyfriend get happy like a little kid and smiling and laughing....
I couldn't understand how that kind of behavior could annoy a person. Unless you're getting tired or bored. ....And when they don't tell you why they're getting annoyed that's all you really can assume right?? ....
