When I moved into my wife's house, I had to go through 30 years of boxed up stuff in my basement. There were a lot of boxes. Two held a bunch of HS trophies I had won back, well, in HS. I realized I had not looked at them since I had packed them when I first moved into that house. Somewhat wistfully, they went into the garbage. I have not had any use for them since of course. I recall I had a Sport Illustrated with Herschel on the cover from 1980 that I sort of wish I had retained.
I got some fairly impressive looking plaque in the mail after I retired from my company, I have not yet thrown it out, mostly because I don't know where it is. I have a diploma cert on my wall here, I guess I will keep that.
My daughter moved from C-bus to Vancouver and fit everything she wanted in her modest sized SUV and drove. I know she had a bunch of soccer trophies, they probably were trashed years earlier. I sort of think "we" should go through out stuff every five years and clean it out, most of it.
