Ok so some of you may remember a thread a did a few months ago about my SIL who wouldn't look after my DD for 10 minutes when I had an overlap time that I needed to leave for an interview by my DB wouldn't be home just yet after all the free childcare I provided them.
I came away from the thread after everyone's really helpful responses knowing that the way to go forward was to continue to look after my nieces but ONLY if it was to help my DB as we continuously help each other out when needed.
Soooo back to today. DB has gone away for a few days with work, he rang me with 2/3 requests to help my SIL with the kids whilst he was gone (school pickups/drop offs) I declined all and said she works out leave when it's for things for her so I'm sure she can do it for her children... every single Friday I pick my younger niece up from school with my DD, they literally look forward to it all week; we have our rituals that we do and we always have a lovely time together, then my DB picks his eldest up when school finishes then gets DN from me.
I spoke to SIL this morning about what the plan was for today (what time would she be picking DN up) seems that she got me confused with the local taxi service and assumed I would be dropping her home later, no I said, I can't do this tonight I have DH family coming for dinner and I won't have time. So she has now decided that she may aswell pick DN up from school then when she finishes if she has to go out to get her anyway.
I 100% know that this is totally fair enough if she wants to but AIBU to think she is just a selfish cow. My DD will be so upset now as she thinks her friend is coming to play and the only reason she isn't now is because my SIL has decided literally an hour before than this is no longer "convenient".
