Convo time again

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"

Convo from today

Son : I'm like a ninja
Me : Huh?
Son : I just jumped off the stairs.
Me : Oh okay, be careful NinjaBoy
Son : I'm not a ninja
Me : You just said "I'm like a ninja"
Son : Ya, I said I'm LIKE a ninja

Too funny
