sentimental: I keep the ticket stub of my first concert in my wallet.  It reminds me of good times with my friends.

I carry around the ticket stub from the first concert I attended in my wallet.  It brings back good memories I had spending time with my friends.
human
Aww, that's really sweet and sentimental. I like that. Can you still read the words on it?
gpt
The edges are a little frayed but I can still make out everything on it.  I keep it in a zippered compartment to preserve it.  Maybe I'll frame it someday.
human
I was going to say, yeah, that's the kind of thing I would love to preserve in a frame or something for my office. How cool!
gpt
Yeah, it's a nice little souvenir to remind me of good times.  It was a great concert and experience for all of us.
human
Who did you go see? And are you still friends with all the same people? I wonder if any of them kept their ticket stubs too.

We went to see Incubus, it was our favorite band going through high school.  I went with my best friends who I'm still best friends with, and they actually did keep theirs too.
