Today the weather was much nicer - clear and in the 60's - so on my way home I had the car window open about 1/4 of the way. I was in the left lane and came up on a car turning left, so I waited until I could move and got into the right lane to pass them. They also had their window open, and their little white Pomeranian was sticking its head out of the window. As I was passing their car, the dog started to bark at me.
So I barked back.
Out the open window.
And then laughed hysterically for 5 minutes straight after what I'd done hit me.
I can only conclude that I either miss having a dog, especially a Pom, or I'm going completely nuts. Maybe both!
