I have a group of very old friends, going back years. I included another friend in this group (let's call her Sarah) & she has enjoyed lots of wonderful social gatherings thanks to me being a kind, inclusive friend. A few weeks ago, I received a phone call from one of the group asking why I hadn't gone to Karen's supper get together... I discovered Karen had seen Sarah and asked her to invite me and Sarah 'forgot'. AIBU to think you actually don't forget to issue an invitation to a friend?? AUBU to think when Sarah pulled up on Karen's drive she didn't think 'omg I've forgotten to invite my lovely friend to this lovely supper. I must call her now !!' I was so upset . I'm thinking it's calculated and she's actually jealous . She said she 'forgot' as she's so 'busy' . How would you guys feel ???
