Common cause unites

There’s a grumpy old guy at my gym that hates that I spend my rest time between sets on my phone. 

Like right now as I’m typing this, he’s getting up to complain.

There’s another guy from the staff at the gym that thinks it’s a good idea to mop the gym while it’s still open. Including squat racks as people are squatting hundreds of pounds.

The grump guy complained that the guy was early and needed to stop. The guy stopped mopping. For once I felt comradery. 

A common cause unites enemies. 

Results cement the bond.

How can you bring people together by simply getting something done?
