I have a friend. We're not that close but our DSs get on famously.
On several occasions though we've been let down by this friend over play dates leaving me with a disappointed DS and us at a loose end. She's v. bad at returning calls etc. So, I've given up making arrangements with her and I've stopped telling DS what plans I may have for him that day in case they don't work out.
This friend wants to see us next week. I said airily that I'd have to check the diary and that I'd call her. I don't think I will call her just to give her a taste of her own medicine. It's not as bad as her behaviour whereby she actually makes the arrangement and then doesn't bother to return calls to confirm the playdate venue.
Am I just just being petty or do you think it would have an effect?
