Yea, I am very skilled at reading nonverbal communication, but it isn't an exact science with a one-for-one translation. It is largely instinctual and educated guess work based on experience and subconscious awareness. [Snip]
[Yes, I'm late to this conversation.]Not having had the best of childhoods[1] I was forced to learn body language growing up. The text I oranged is one of the reasons a lot of my body language is deliberate and exaggerated to a degree. I hate being misunderstood and I'm told I have difficulty modulating tone in my delivery by some people. When it comes to facial expressions, it's my eyebrows and mouth that will tell you my intent as that's what I exaggerate. I'm not entirely certain when I started exaggerating my body language, but I know I started doing so more when I started working at the factory I'm at now.[2] Between that and my dry erase board, it makes communicating with my two deaf coworkers and my many ESL coworkers a fair bit easier.[3]
For a examples: When I roll my eyes and I want to the person to know it's a purposeful motion, I'll follow the motion with my head in a small but noticeable arc. Disappointment is indicated with a visible and somewhat animated shoulder and head slump. That sort of thing. Think of a mime or other stage clown performing emotions in a routine/skit.
[1]I'd rather not get into it. Suffice it to say court-ordered family therapy.
[2] I may be 5'5" (165cm) but I weigh 222 lbs (100.7 kg) and have to wear a US men's 3XL labcoat for my shoulders alone. So that tends to spook some folks when I'm walking quickly in their direction.
[3] Not sure if my no-visible-teeth smile is considered abberant or not.
EDIT: Yes, fashion is absolutely B.S. Standardize size, make pockets functional.
EDIT 2: [completing above thought] As long as it's not ratty, covers your nethers, doesn't 'clash', and you like wearing it, it shouldn't matter.
