Happiness Gauge

How can the people around you tell if you are happy? What do you use for a happiness gauge?

For me, if I'm singing while I work in the kitchen, or while I'm driving, you can tell I'm happy.

I caught myself singing today. I was on my way to the grocery store, and I was singing. What was I singing? I can't recall.

On the way home I was singing an old song with it's roots in the worry of the Mamas of Irish lads who went to war.

"Oh Mrs McGraw," the sergeant said, "would you like to make a soldier out of your son Ted,
With a scarlet cloak and a big cocked hat, oh, Mrs McGraw, wouldn't you like that?"
With your too rye ah, fa the diddle ah, too rye, too rye too rye ah
With your too rye ah, fa the diddle ah, too rye, ooh rye ooh rye ah
Lav beg the cracker oh!

I don't suppose it really matters what I am singing, but the fact that I am singing is note worthy.

Years and years ago, when I would sing in the cars, my kids wished I would not. On one occasion, one of the girls went so far as to threaten to jump out of the car while it was moving if I did not cease my singing.
