Dear Abby: I’m upset that we planned to attend an exhibit together, but I got sick and she went without me

DEAR ABBY: A close friend, who I also work with, agreed to attend a paleontology exhibit with me approximately six months before the exhibit was scheduled to open. We were both excited about it and talked frequently about how much fun it would be to attend together.
About a week after it opened, I was unexpectedly out of the office for a medical emergency, and my friend attended the exhibit without me. Am I wrong for feeling upset? She keeps telling me to get over it and is not being understanding at all. Am I overreacting? — BOTHERED IN THE EAST
DEAR BOTHERED: If the exhibit was finished before you were able to go, you shouldn’t blame your friend for seeing it. If, however, the exhibit was still on, I can’t blame you for being upset that she went without you. The question now is, is this worth ending a friendship over? (I hope not.)
