Parents aren't always fun, I've known some seriously messed up parents in my time, caused me to forgive every annoying foible of my own.
Some kids have no problem with it, some do. Shouldn't get upset with people who had issues with learning the truth about Santa when they were little, can't really control what random thoughts ran through your head decades ago.
I'm not upset, I'm just trying to get a few of the overwrought to not pass on that personal flaw to their kids.
