True.

Unfortunately, I can't remain humble when my date starts a brag-fest like high school kids.

Humility is sometimes taken as cowardice or shyness.

My rule: unless it was TERRIBLE, I always try for a 2nd date. Too much variability in a first date to draw meaningful conclusions.

Truth....was she nervous, was she not into where was picked for the date, did you not get her humor yet, did she not get yours, etc

Yes. No one want's to hear about your gap year in Bolivia.
