Question

How dou you know when someone is really deep? What makes a person deep?

Answer 1

If you know a person genuinely has a greater understanding of a particular subject than you do, then that makes them deep (to you) in that specific area.  

In people of about the same age, it's normally the case that someone will be deeper than you in some areas, and shallower than you in others.

You should also consider that it's possible to be genuinely deep, AND wrong.  Many of the greatest thinkers in history have had completely opposite opinions.

Answer 2

When they tell you things you never knew about them

Answer 3

It's what they speak and that's how you know. It's a matter of opinion of what you consider to be deep. What if your friend tells you that her Mom told her that she was a mistake and she doesn't love her but wants her to die. That's deep what her mother said. Or something very serious and very meaningful.

Answer 4

uhh...when she echos?
