I feel perpetually 17. I am especially aware of how young I feel now that I am no longer in my 20s- I spend a lot of time walking around thinking that people must say to themselves, "those can't be her kids!" then I realize that of course they look like they're my kids. And I totally look like a mom, the kind of mom who drives a mini-van and puts her children in time out in public so people can walk by and try to decide whether or not they should call Child Services.
But despite not actually being a teenager, the reality is that I am starting over when most people are just starting. Hopefully that will give me some wiggle room to get things right over the next oh... 65 years.
