I do it religiously.
But I don't do it on Twitter.
You see, every night when I put my youngest to bed he pretends to be a bird. He's the baby bird and I'm the mama bird. We communicate by tweeting, literally.
Goodnight is "tweet tweet".
I love you is "tweet tweet tweet tweet".
It's not a complicated language. Most of the meaning lies in the inflection.
It's one of my favorite parts of the day.
