Definition: the miniature vacation that occurs when you get to drive in your car without your children.
When there are kids in the car, the radio stays low, the music is usually child-oriented, there is a lot of buckling and usually some screaming. Even if they are all asleep, they are still there and you have to be aware of them.
A car trip without the kids can be like a little getaway. I put on very loud, very non-child-friendly music. I sing. I dance. I go crazy (while still being a responsible driver). If I am not in the mood for music, I can drive in silence. Complete silence. Like a spa, only without the masseuse and gurgling fountain.
I don't get to be by myself very much, so I take advantage of time on my own whenever I can.
Solo car trips are a treat for me. I don't think my husband understands this, but I know that all of you other child-haulers get what I am saying.
Never underestimate the recuperative potential of a car trip on your own.
