How someone treats a waiter or doorman can tell you so much about a person.

I went through a period when I was rebellious and a mess of a person.

If a guy treats me respectfully and the waiter demeaningly, I'm turned off.

As soon as you start feeling like you can't trust the person and you need to check his phone or have his Facebook password or look through his messages - as soon as that trust barrier is broken - it's hard to keep a relationship going after that.

You can't tell someone they are wrong about their own life.

You can tell a lot about a person from his underwear.
