One of the main reasons I'm not a big fan of Christmas, is that it was introduced by the Catholic church.
And as such, it has some fairly nasty traits similar to what happened in the parishes as well.
What I mean is that most people "try to be nicer" for this period. However, they don't care about being complete jerks the rest of the year. Which is very similar to what happened at confession: a person could do the most horrific stuff, and then confess and "clear his/her conscious" by paying penance (usually a bribe for the pastor).
Anyway, I suppose that an effort to be better for a short period every year is better than it not happening at all.
I do not know what I don't know,
if I do not know what it is I don't know.
