O has been engrossed cataloguing his Match Attax football cards for about 30 minutes now. His attention to putting them in the correct order is fascinating, but not entirely unexpected when I think of myself at his age almost 40 years ago..........Panini Euro Championships 1977 sticker book, complete! I can remember where I was when I opened the packet containing the final card I needed, what it was, and who bought it for me.

How's that for cataloging?
