Word MOTORCYCLE starts with an M and ends with LE. If you spell MLE it sounds like Emily. I kept using the abbreviation at first, trying to be funny, until it naturally evolved into a real name, and it stuck. Originally, I had no intentions on giving her a name. Go figure.
"Emily, wanna go for a ride?"
"Emily, did you have a good ride today?"
"Emily, your face is full of bugs"
"Emily, how are you doing today?"
I'll tell you one thing - she is such a good listener.
