A few thoughts about the most dysfunctional time of the year.
1. Leave your kids at home.
You are shopping, the store is packed, and everyone is in a hurry. This is all annoying, and bad enough on its own. It is made so much worse by the mobs of children crying, or singing ONE LINE of a Christmas song REPEATEDLY. Just leave them at home, it will make stores infinitely more tolerable.
2. Turn the heat off in stores.
Stores are packed, and each person generates heat. Yes it is cold outside, but when you cram several hundred people in to an enclosed space it heats up fast. People are pissed off enough due to the season, do they need to sweat too?
3. Actually help someone in need.
Give a hobo a twenty. Yeah, he may just get loaded with it, but he will be happy for a few minutes.
