SO my 14yo sister is staying with me, my partner and my son, for a bit in the 6 week holidays because she lives about 100 miles from us. For days now she has stayed up late then refused to get up, not at an unreasonable time. Ive been trying to wake her around 10am but her not getting up til 12 or 1pm. Last night i went to bed around 8pm because of a migraine and woke up to her sitting in the living room painting at 4.30am, she immediately went to bed without me saying anything. I get up this morning with our boy and realise theres watercolour all over the sofa which wont come off.
AIBU to be annoyed by her attitude recently and go get her up to try clean it? Surely shes old enough to deal with the consequences of not going to bed at a reasonable time.
