What an optimal relationship should be like

You scratch my back, I scratch yours.

This is the definition of teamwork.

I ride horses at a stable and ( sad but true ) one of the horses died today.but he would always jump over the fence ( hes a Morgan horse) in thr halflingers paddock and scratch their backs. His name was Forrest :'(

Later on that kid slathered peanut butter on his nuts and let the dog lick it off
