It is a friends birthday next week and she went away for a holiday on Friday. I have been ill with chest infection this week so hadn’t sent her a card in the post . I went to work on Thursday and did a detour to her house and delivered card into her letterbox . I didn’t knock because I was in a rush to get to work. I text her later to say that there was a card for her in letter box . Received a very sarcastic reply that she saw me drive away and it would have been nice if I had bothered to stop for a quick chat . Was very taken aback by her reply and apologised explaining I was on my way to work and hope she has a lovely birthday. She replied saying that she had forgotten ‘I like to get to work early’ very passive aggressive and not what I would ever think if a friend bothered to deliver a card to me ! Am I being unreasonable to be massively pissed off with her ?
