I’ve moved into my first home and a relative gifted me some towels that had never been used but were sat in their cupboard for years. Other relative brought them to me as they’d visited. Few days later on the phone Relative asked other relative and said ‘did she like her towels?’ ‘Yes she said they were nice’ then relative said ‘oh well I thought she would have rang me up and thanked me’ in quite an annoyed tone apparently. I’m due to see this relative at the weekend so was going to say thank you then. Or Aibu should I have rang them up and said thank you?
