Sorry this is long!
SIL and my brother split up around 6 months ago, she has just started getting out and visiting some family and making new friends (Great as far as I am concerned!) However she went away this weekend and has not come back, all 3 boys are off school for no good reason. She is off to bingo tonight, AIBU to think her boys should be at school? I know she is having a hard time with her and my brother splitting up but surely she had the whole weekend of getting pissed for her me time?
Also the eldest gets really worried about missing school, I remember the feeling when I was a kid if I had a day off...
