sentimental: I recently drove past my old high school and had a nostalgic feeling. I started thinking back to when I was a teenager and memories of my old friends.

I recently had to go to my old High School. And as soon as I walked in I started thinking back to my teen years.

Very cool, was it for a high school reunion?  Hopefully it brought up good memories!

The memories were good. I was invited by the football coach to talk to the football team.

Awesome!  Hopefully you gave them the motivation they needed for the new year!

Hopefully, and thank you!
