> Actually, I giggle a lot. Sometimes it bothers me, and I feel like I'm being really immature or annoying, but then I figure that I have enough friends who don't seem to mind , so it can't be all that obnoxious, and it's just a sign that I'm enjoying life. :) Right?

I tend to be a rather giggly person, m'self. Frankly, I don't concern myself with whether or not it's obnoxious; nobody I care about complains, and everybody else can go hang.
