I work in a school (separate school from where our DC attend). DH also works full time. As I work in education, I have amused and entertained the DC for 6 long weeks on my own.
The DC return to school on Wednesday 7th. I return back on Monday 5th. DH knows this. We have very limited childcare options.
DH has now announced he's used his 2 last remaining annual leave days for a long bank holiday weekend away with the lads. Apparently he "forgot" that the DC need sorting for 2 days while I'm in work 
I don't give a shit that he's going away. I do however give a shit that he's been utterly self centered and now we are screwed about childcare for the 5th and 6th of September. He just automatically assumes that all childcare responsibilities fall on me by default.
