“17. Flaking. As someone who used to flake so much Kellogg’s wanted to sponsor me, I know just how much people loathe last minute canceling and unexplained absences. If you know in advance that you don’t want to partake in festivities, I’d recommend saying “no” firmly, because that’s a lot less disappointing/rude than leading inviters on ‘til the last minute. ” Tru dat. Guilty.
