..would you text the parent of the house they said they were spending the night to check it was OK with them?
Because DS1's very nice, middle class parents don't, apparently - leaving me to text them when I settle down for the evening, usually about 9pm, to say "Just letting you know X is spending the night here, they're all watching X film atm.
There is no way I would let DS go to sleep at a friends house without checking with the parents first.
DH and I aren't sure if we were just really naughty teenagers, or if we are over-protective parents, or if DS1's friends parents are a bit slack. (DS and his friends are very honest and sensible, but still, they are 14yo boys with big ideas.)
