Those of you with no curfew at all- how do your kids get home?
Do you just make sure you don't drink every night so when they need collecting at all hours you're sober? Or do you pay for taxis?
I don't drive (visual impairment) and dh had a very long commute in those days, getting up at 5 to go to work, so dc just knew that this was another thing they had to plan for: if I want to go to this party, how am I going to get home? Lifts have never been on tap in this household.
They always knew they could ring in an emergency, but they also knew that this didn't preclude planning in advance, seeing if they had the taxi money, checking the bus times (we live in a city where there are some buses of not London standards), making sure if they needed a lift that it wouldn't be too much of an inconvenience. In short, behaving like adults when they made their plans.
For ds, the plan often involved very long walks- he is a big strong lad and there is not a lot of knife crime where we live. This was the lad who missed his school bus on the first day in Sixth Form and walked back from a different town- took him the best part of 4 hours but it wouldn't have occurred to him to ring us at work and inconvenience us.
It also helped that dh and I are not heavy drinkers by MN standards so not drinking on the one night a week a dc might be out didn't seem a horrendous sacrifice. I rather liked the idea of them enjoying themselves- particularly dd who had lost a lot of her earlier teens to illness. If dh and I were at home anyway, we could have just as pleasant a time talking and watching a film without alcohol.
Dc didn't go out partying every night- they couldn't have afforded the alcohol, let alone the taxi fares. Money wasn't desperately tight when they were teens but tight enough that they knew everything had to be planned for.
Once they got to 18, I had no difficulty just falling asleep when they were out. Ds is 20 and still lives at home- he is a night owl who goes to the gym at midnight to avoid the crowds, I'd be permanently sleep deprived waiting up for him.
But we absolutely expected them to be polite about things like letting us know when they'd not be home for dinner.
