Consider this scenario:
A colleague from work (be it a boss or another coworker tasked with coordinating something) sends an e-mail to several people including you, whereby it's expected that all of you respond and put others in cc.
Now you go to the restroom and by chance meet this mail sender and express your position to him in person, such as "About that e-mail - everything works for me".
Now you're in an awkward situation:
- If you respond via mail "Everything works for me", it's weird to this person why are you writing this again because you just told them that a minute ago in person.
- If you don't respond to this mail, other people involved see you didn't respond and might think that's to show disdain or due to negligence.
What to do?
