Approaching Christmas At A Different Angle

(It is Christmas. and two of my brothers and my dad are sitting at the kitchen table looking at a Christmas tree ornament my mom has made out of wrapping paper.)

Brother #1: “This paper is cut at a weird angle. I wonder what the angle is.”

Brother #2: “You need a protractor. Or better yet, a protractor app.”

Dad: “I have a protractor app.”

(This is not an unusual conversation in my family.)
