Me deleting is so controlling. I'm usually not a micro manager, but she was playing stupid. She did make an effort to delete but there was some residual and she never cleans out her inbox. Old stuff from years back all "group" emails with her and OM on them. It was all within a good conversation though and I just did it.

There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
