... because I can't get it to work right. DSs are 13 and 15 so spend a fair amount of time at home on their own. If I say you're grounded, they say Yes Mum, then proceed to go out as soon as I'm not around. Is it the wrong age? Am I not dedicated enough to see it through - can perhaps manage 1 evening if I'm in the house with them. Once I said to DS1 in a heated manner(he was 12 at the time) "do not go through that door" so he climbed through the window & pretended he thought this was perfectly ok. I feel like that mother in the Guardian's living with teenagers column sometimes.
