Laughing

Have you guys ever laughed at something really funny for one moment, and then laughed about it again < 30 minutes later? With the same people? In the same conversation? I have. On many different occasions.
I was just thinking about it when I was putting the sheets back on my bed: is that a sign of being socially awkward? Like, still being in the moment of the funny story and not wanting to move on, even though the people you are sitting with have moved on with a different conversation subject?
I tried reasoning that the reason I do that is because I like being happy. This may be hard to believe for those of you who have read all of my blog posts from the beginning, since I tend to bitch about a lot of things...Hah, the next post I'm going to write right after this one is no exception. (Yes, you guys are going to get two blog posts in one day! How lucky are you? I figured as soon as I get the thoughts in my head, I should type them out immediately. Or else I'll forget and my passion for the topic will have vanished.)
Sometimes I think that I am more socially awkward than other people. And then I meet those people who think they are even more socially awkward than myself. But really, I think I am. I tell people that I'm better at listening to people than speaking with people: maybe this is just something I say to cover up what I'm actually like.
I don't know, this is as far as my thought processes went. What do you guys think?
Love.
