Son "I like pulling off scabs it's fun"
Where exactly does the fun come from? The thrill of ripping it off in one tug (like peeling a beer label)? Seeing whether or not you have to yell "MOMMMMMM I need a Band Aid"?
Deciding if you're going to get up & put it in the garbage?
I'm not sure where this thrill in all of this is as long as it doens't end in "Ewwwwww"
