A friend of mine, that I know is very insecure with herself, always stands around with her arms folded in front of her chest. Almost as if she is hiding behind her arms. Its not like she has a big chest she is hiding. Last night I'm at the gym banging out my hour of cardio, I look around and I see at least 3 or 4 girls walking around with their arms folded in front of them. Each of them seemed as if they were hiding something. One girl, really cute (young too), walking around with one of the salesmen showing her around walked around the whole gym like that. Do you think this is a sign of insecurity or purely coincidence?
