I became a teenager in 1967. I was the oldest of 5, so I never had the house to myself overnight, and rarely during the day. We had 1 car when I got my license so driving was a rarity. I was saving as much money as I could for college (I knew my folks couldn’t afford to send me) so buying a car was not even an issue for me - I rode my bicycle everywhere.
This was long before the age of cell phones, but if I was going to a friend’s house, my mom knew where I’d be and she had the phone number. I knew when I was due home, and if I was running late, I knew I had to call.
Not that any of that was an issue - I was *such * a goody-goody!!
With my own daughter, I knew her friends and I knew where she’d be and when she was due home. We got her a cell (and a car) when she started driving, and she knew to call as necessary. For the most part, she was a good kid, and when she did take advantage of having the house to herself one weekend and we found out, she realized the value of parental trust, and we worked thru that pretty quick.
Now she’s 800 miles away in college. I worry, because that’s my job. But she calls, sometimes just to chat, and if I get too worried, I’ll email her or leave her a voice mail and she always gets back to me. Of course, she’s nearly 22 now, so I try to let go. But she’s still my baby.
