Lying is a big deal. Went on a date with a very nervous, but also very intelligent and kind woman... Unfortunately, when we started talking about music, she told a verifiable lie (claimed to have seen a band I like at a festival, when I know for a fact the band did not play at the festival, and when pressed even lied about some of the songs they played) in an attempt to relate to me. I thought there was some potential up until that point, but that ended it for me. If someone lies about the small stuff I can't trust them to be honest about the big stuff, and trust is at least as important as love in a healthy relationship. Too bad, but bullet dodged.
