Made a joke about a friend in a group setting. It didn’t land at all well and looked like I was trying to make her look silly. She tried to brush it off, I redirected the conversation and made myself look awful and the conversation awkward. The joke was about something silly - the sort of thing we can all do but for some reason on a given day, we can’t do it (like work the microwave at someone’s house or get the lid off a drink). It had happened earlier in the day, we’d laughed about it. For some stupid reason I brought it up in the group later in the day and she didn’t like it at all. I’m not mean spirited in the slightest, don’t make jokes at someone’s expense generally. It just came out (I’d had a drink - we were having a laugh, no excuse but relevant context). Now I feel awful - like I was trying to make her feel stupid. We spent the rest of the day together and she was fine but it’s bothered me all week. Do I just get over it or apologies belatedly?
