|Facebook never forgets...|
With regard to this memory, the main issues are that a) I don't like the thought that there are details of my life that I can't easily recollect, and b) I now want to thank someone for something that happened seven years ago but I don't know whom to thank or what to thank them for. This annoys/bothers/upsets me now, even though I clearly (or more precisely, vaguely) did the thanking seven years ago.
If we were hanging out at all seven years ago, go ahead and assume this is about you and remind me of the purpose behind this post. Do that, and I'll owe you yet another debt of gratitude. Hey, at least seven years from now we'll stand a better chance of remembering how we got into this vicious cycle... :-)
