Years ago, a co-worker was debating whether or not his new daughter would be introduced to Santa Claus.
His conundrum was whether or not he was lying to this child, and if that was a precedent he wanted to set. At that time, I already had two kids, and we were full on into the “Of course you lie to them” mode, so I explained that lying to your children was probably one of the few things that would get you through parenting relatively sane.
