It brings back good memories I had spending time with my friends.', "Aww, that's really sweet and sentimental. I like that. Can you still read the words on it?", "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.", "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!", "Yeah, it's a nice little souvenir to remind me of good times.  It was a great concert and experience for all of us."]
sys_response: 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.
