Basically, DTD2 had a (short) play on the laptop last night, and apparently DTD1 asked if she could have a go, and was told no. She was on the laptop herself tonight and had had more time than her sister, so DTD2 asked if she could have a quick go.
As you may expect, loud argument ensued, and DTD2 was told she can have a go tomorrow night. They carried on arguing, and i said that if they can't stop messing about DTD1 should get off the laptop and they will both be banned from it except for homework.
DTD1 to my extreme surprise, instead of shutting up, closed the internet window, intent on logging off! I told her to stop being silly and she should just stop arguing and carry on playing - that was what i expected anyway. So she complained about it, as though i had told her to switch off.
I was thoroughly annoyed by this time and answered that if she's that daft (yes i know it wasn't a nice thing to say) she can blardy well switch it off then. She then stormed off crying, and i am torn between feeling bad that i've upset her, and not wanting to go back on what i've said because i feel justified...so, AIBU?
