I have a friend I've known since college. We had children the same time-ish and since they've been at school we have fallen into the habit of meeting for tea once a week. It was most weeks but not set in stone eg occasionally one of us would cancel for dentist/other commitments. Last time we met I mentioned I couldnt do the next week since DD really wanted to try a new after school club. Friend was a bit sniffy about being bumped, but jokingly so. I thought. Anyway, she wont answer the phone or mail me back now. I have sent an apologetic 'Sorry, DD really wants to do the class, this is the only night its on, can we meet another day, really want to keep meeting up' e mail, and have texted her too. Have I been totally unreasonable here? And how on earth do I make amends, especially since Im getting annoyed myself now. Theres only so much I am prepared to grovel!
