Sometimes we have to trust our kids.
I have two children that will be 19 & 22 this April & May.
They have their own vehicles and they bought them and paid for them. They've been doing things on their own since they were 17. I trust my kids.
Yes, we had our times where we didn't agree on curfews.
But when you have someone else driving, and you have a bunch of kids going to a concert, either don't let them go to the concert, or just know that coming home on time isn't an option. That is totally up to the driver.
We all need to talk to our kids more. They are at that age when they are trying to find themselves. In between child and adult. It's a difficult time. But what I found is that talking to them, taking them out for lunch and just being mom and daughter, really kind of smooths things over.
If it were my kids and they said they were going to a concert and they weren't driving, I guess I wouldn't expect them to be on time. I know, when I was a kid, that happened to me. I couldn't get a ride home. And back then , we didn't have cell phones.!! So if you talked to her and she said it would be a little bit longer. As long as they came home safely and had a good time, I guess I wouldn't worry.
But that's just my opinion.
I trust my daughter & my son. They are little adults. :-)
Believe in your kids. You seem to be a wonderful mom. Just know in your heart that you are a good parent and trust in your children.
Trust in your girls. Trust YOU DID A GREAT JOB!
