HEY DRIVERS!! stop makeing your passengers feel uncomfortable :P
Crossed Arms: This is when the arms are neatly folded across the chess to protect the heart, lungs and other vital organs as well as breasts in most womens cases. We will usually cross our arms when we feel
nervous,
negativetowards something/someone or are feeling
defensive (such as when someone is making fun of our top/dress. and we cross our arms in response). Monkeys have also been observed to do the exact same gesture when they feel they are in a threatening situation. You can commonly see the crossed arm gesture in public meetings amongst strangers, elevators, cashier shopping lines or any place where we feel
insecure or
uncertain of our surroundings.

Crossed Arms With Fists: If, as well as crossing their arms, the person has clenched fists as well, this is a strong sign of
hostility as well as
defensiveness as mentioned in myPalms & Thumbs article. This combined gesture is an aggressive and attacking attitude that you should watch out for. This gesture is often times found in jobs that require hostility and defensiveness, such as bouncers or police men standing guard (patrolling policemen rarely cross their arms as they have a weapon for protection, which is enough. The same goes for anyone wearing a body armor, they'll never cross their arms).
