You're right, I didn't say it was in fun... With Santa, I guess it just didn't occur to me that I had to clarify that. I have no overwrought childhood trauma associated with Santa Claus and the "truth".
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.
