My Manager: Could you help "other manager" (OM) they need some very simple code changes.

Me: sure that will only take a few minutes *adds 15 lines of code tells OM one single line they have to modify*

Some other manager (SOM): Hey how does this work, I'm confused, do I need to do anything?

Me: Yes see the email chain you were copied on.

SOM: Actually let's have a meeting instead and all discuss this.

Goddammit this was a simple change to make your life easier now you are wasting everyones time by not reading the email
