There are so many different lame lines and behavioural traits I pick up on, I couldn't possibly mention them all without writing a few novels, and everyone else has pretty much given the ones I would equate to a red flag moment.

However for me personally, everyone is considered a red flag. I don't really trust anyone, until I get to know them extremely well.

And no I don't have trust issues, but I do have to know someone very well before I go any further in a relationship with them. My internal instincts are good enough for me to determine how comfortable I am with another.
