This sounds fun.
As a comment here on the blog, leave one memory that you and I have shared, regardless of how well or how little you knew me at the time, just about everything is fair game, so long as you remember it, and I at least have a vague recollection of it.
Next, repost the basic instructions on your own blog and see what turns up. You may be surprised, you may not, but in general, memories with friends are never bad things to dig up every now and again, heck, maybe you'll even find something to jot down in the dusty old journal.
