[usr] I was so embarrassed at work last week.  My boss keeps bringing up a mistake I made months back. [sys] That happens, you have to acknowledge mistakes to learn from them. [usr] I did though, I've apologized repeatedly.  we've discussed it multiple times.  It's hard because she brings it up in front of others. [qst] [None] [bhv] please give me some advices.
Oh well that seems improper, you should bring it up to her supervisor.
A few months back I make serious mistake during an experiment.  Thankfully it didn't actually destroy the work.  I am still super embarrassed thinking about it.
