Some years ago, I reported in the old board about my one and only embarrassing incident in which I forgot to leave the donation during a meeting. It was a Rochester favorite and I did not realize my mistake until I was almost home. She kindly forgave me and insisted that I wait until next time to make it up to her, which I did a month later.
Well, it happened again today for the second time in my "career". It was a local favorite and I realized to my horror that the envelope was still in my jacket when I returned to my office 30 minutes later. I immediately called her to apologize profusely and offered to deliver it. She graciously laughed at my absent-mindedness and assured me that I can wait until next time, which I plan to do within two weeks.
I still feel bad about it. She even served me lunch!
