My best friend is Sue, and she has a close friend named Erin. I am friends with both Sue and Erin on FB, although I rarely see Erin in real life and we don't really get along. Erin is a vegetarian, and if anyone eats meat around her, they are subjected to comments about eating "poor innocent little animals".
Recently Sue posted a funny picture about bacon on my FB wall. Erin responded something about "murdering poor innocent little piggies". Since the picture was supposed to be funny and lighthearted, I deleted Erin's comment.
Apparently Erin noticed that her comment was gone and posted "Sue, you b****, why did you delete my comment?" Note that it is common for Sue and Erin to jokingly call each other "b****", but I would be uncomfortable with Erin calling me that.
Sue and Erin went back and forth over a few times about the deleted comment and then dropped it.
Should I fess up to deleting the comment and apologize? Or should I just let this go? And was it wrong of me to delete it in the first place?
