I remember Gram saying the same thing to me when I was a teen. I feel bad for teenagers today. It's such a complicated world. It used to be simpler. And we used to have so much fun, when I was a kid. You can't have fun like that as a teen today.
I know quite a few teenagers today. But when my kids were little, teens kinda scared me. In fact, they still do. They can be very unpredictable, to the point where you can't always even say that you will be safe if you walk by a group of them on a dark street.
I'm very unsure about where I stand with most teens. They can be so uninterested in anything adult. They often make me feel invisible.
Often, teenagers piss me off. They can be quite obnoxious on occasion. They can be very condescending.
On the other hand, sometimes I have a good conversation with one or two of them, or learn things about the kinds of things that they are going through and trying to figure out and my heart really melts for them.
(Of course, they aren't ALL good. Some of them still just make me mad, no matter what they do.)
