It's a reflection on how you view others.I know what I said was really mean. It is not a reflection of who I am!
I find myself wondering if the decision not to 'take things further' was entirely yours or whether, having met you, she decided you weren't really her type and your bravado now is an attempt to camouflage that.
Personally, I hope she hooks up with the guy behind the counter because he sounds super.
