This little chalkboard slate hangs by my front door.
Every December we have a party: Christmas Game Day. It's a big deal around here. Last December I wrote on my chalkboard "HAPPY! !!GAME DAY!!"
That message stayed until about Valentines Day when I finally erased the GAME DAY!! part of the message. But I was in a hurry (and not in the greatest mood) and couldn't decide what to put in its place. So I left it.
Today I noticed it again. And instead of the grumpy mood of that day, I'm in a great mood on this day. And I realized: why do I need to be told to be happy about some specific thing or event?
"!HAPPY!!" is enough for me.
