Monkey see, monkey do

Me: Ben, why are you doing that? (putting his water bottle somewhere dirty)

Ben: Well, Ethan did it.

Me: if Ethan jumped off a bridge, would you do it too?
Ben: yes

Me: what if Ethan jumped off and got hurt, would you still do it?

Ben: yeah, if it was a spiky ground or a soft ground....(trailed off in thought)
