I really differ depending on what crowd of friends I'm around. I'm not two-faced but there are groups of friends that some thing go and others things don't, you know?
People I don't know or just met I'm very polite and sweet, very caring and my close friends always say "Don't let Michelle around a stranger, she'll jump off a cliff for them." just because I like to do what ever they want for them. That always makes me mad because it's just I'm very trusting until someone gives me a reason not to, so I trust strangers more since they've never hurt me. That's odd...I know.
Around my close friends I'm a little louder and random and I'll make little rude comments towards some of them (the ones who start it first!!).
A very sweet but tough little munchkin. Hehe. =] <3
