Don’t wrestle that pig.

A customer once told me, “Arguing with an engineer is like wrestling a pig, the more you do it, the more he realizes he likes it.”

Turns out knowing when the argument needs to come to an understanding to keep things moving and when you are wasting time is a skill.

Cut your losses when able, drop the argument.

PS: This isn’t limited to engineers, there are combative types in all jobs.
