Sometimes I’m unsure if I should point out another person’s mistake. For example, someone recently accused me of not confirming I will do what they had asked me to do in an email.
I checked my sent folder and I indeed had replied to them. Should I bother pointing this out?
Their message was along the lines of "you didn’t confirm last time and please make sure you do so next time". This is the first time this has happened with this person.
What other factors should I consider when deciding whether to bother to reply? I also want to have a positive image but I guess human mistakes like this don't happen frequently enough to affect it.
The end result I want is productivity, not some mock jury and court room.
A more general form of this question is "when should you defend yourself and when should you let an well-meaning accusation role off your shoulder".
