In brief: my cousin and his girlfriend have a child starting the same school as mine (they started on Tuesday.) His parents often look after him when they are working (she works part time, he is full time) but they on a month away that has been planned for some time (almost 12 months.) I am a SAHM but am now, as of this week, doing more freelance work. Previously, my work fitted around DS who did two days a week at nursery.
I was asked at 4pm on Wednesday if I would have their son for Thursday and Friday this week, in a very 'while you're picking your DS up...' kind of way rather than that they had been caught short, sent at almost 4pm the day before. I explained I was working but could help out on Thursday but not the rest of the time. I did that, and it was fine but was also then asked if i could mind him Monday too. I said no as I was working. Today I got a text at 2pm asking me to pick their chid anyway as one of them was running late. My DH said (the text and then call was while I was having a Skype meeting) after that we can't be back up and pointed out they knew we / I / he (we both work from home) was busy. Also, its not like this is unexpected (as if it was, I would be happy to help.)
They are not, it appears, not speaking to us.
AIBU...?
