In reply to Tall Clare:
I've got a few things. I ride my motorbike so little it's noy worth keeping it, but I can't bear to get rid of it. It reminds me of my dad, mates I've lost that I used to ride with, and happy times from when the kids were little.
Another thing is my daughter's footprints in paint in a simple frame from when she was 2 months old. Every time I look at them I remember the kids when they were little babies and toddlers.
Other than that it's mostly photos that provoke memories. Some are in albums, some on the laptop and some prints in packets that only see the light of day once every 7 or 8 years but I couldn't bear to part with them as they're all photos of friends, family and happy times.
Most of the other stuff is completely disposable.
