Truth: Elbow holding is always a sign that something nutty is about to follow.
Also, my kids discovered that the term for that extra bit of skin on the elbow is WENIS. Which they, of course, love and use all the time. My 7-year-old made up a song about it.
Anyway, my plan for any future unauthorized elbow-holding is to loudly say, “LET GO OF MY WENIS.” I can only hope that I am in a very crowded, public location when it goes down.
