Have you noticed that people who doesn't like the rain tend to look down, make themselves smaller and walk as fast possible when it rains?

On the flipside, do you know anyone that loves the rain? They don't look down, they bask in the rain, it makes them happy and their bodies shows it. 

It's the same thing with knowing how to read people on a daily basis. Do you notice people's body language and base your conversations off of the vibe they are giving off?
