It is possible to tell how a person feels or what they think just by observing their body language and looking at their eyes. The question I have is if you are good at reading these signals and telling alot about a person just by looking at them. Do you possess this skill? Personally, I am sort of clueless when it comes to this; I find extended (sometimes even short) eye contact awkward and when speaking to someone, I pay all my attention to the words and tend to become blind for body language and eye movement. However, I find it quite easy when observing others, to pick up if they are expressing interest with their body language. Can you, personally, tell if someone is sad, happy, angry or in love etc by looking at their eyes and by reading their body language? Keep in mind the question is not in the sense that you have the therotecial knowledge, but if you actually can pull it off in pratice. I sort of envy people who possess this amazing skill.
I one time saw this lady crying into her phone. Through a series of process elimination, I was able to figure out that she was not extremely happy, she wasn't confused, but upset. I don't want to say that I'm psychic but I'm pretty good at detecting things
