can you read people well?

It's easy to grasp ones emotions or physical state. I mean to say good at gathering subtle hints and queues to what someone is thinking? Especially others opinion of you! I have to say it's quite awkward when you find someone is judging you without even doing anything to suggest they are!
I never understood why people want the power to read minds? Why hear the cold truth to what you already guessed yourself? lol

Yeah sometimes, like when they ask a question or need an opinion or something.

Other day a girl/friend I'd just met recently mentioned she'd been in a deep depression in Feb/March.
We started talking.
After she spoke for a while, I asked her could I ask her a few questions.
So I asked about 20, slowly, over about 45 mins.

After 15 mins she folded her arms.
Arfter 30 her eyes watered a little.
Finally she just said, 'Stop, Stop Stop!"...and stood up and walked around.
So I stopped, hadn't seen the time fly.

Apparently one was off, but the rest were accurate.
She was a little freaked out, but we're friends, so it was ok.
Now she's texting a lot, but I think she's reading into it too much maybe.

That sort of thing happens quite a lot with people.
I can't sense much from people unless they open up a little tho.
I definitely don't set out to analyse/read people.
But I'm told I can 'read' very well yeah.

Body language, tone of voice, and the energy ppl give off are my friends.... It's tiring sometimes but I appreciate the gift I have.
