1) The word ‘webinar’.
2) Receiving 1-word emails (business OR personal).
3) Parties or other social gatherings that devolve into everyone showing each other YouTube videos they think are funny.
4) Eight year olds with cell phones.
5) Those creepy sidebar ads that show someone’s teeth going from white to yellow and back, or their belly fat appearing and disappearing, or their face wrinkling up and then de-wrinkling. Ew.
