general note to the world

  "If you know there is someone who is interested in me, please let me know. This goes double if I appear to be completely oblivious (I almost certainly am).
  This goes double if you know someone is smitten/in love/ etc. with me and I appear not to be aware. I can be remarkably obtuse, and having outside assistance in spotting this stuff would be helpful. And might possibly make things less confusing in my life (unlikely but a guy can dream)."

Another general note to the world

  "Do not under any circumstances assume that I remember any particular conversation/event/encounter/etc. I have had with you, unless you have since that time heard me refer back to it or discussed it with you or otherwise proven that I do recall it.
  I have an *atrociously* bad memory. Both on the minor level of easily forgetting names, and on the major level of forgetting entire relationship-changing conversations with people I love[1]. So if I appear to be operating counter to something I've discussed with you, or seem to be ignoring something you've asked me to do/not do/etc. Please assume that it is because my brain is about as good at retaining memories as a rusted-out colander is good at holding sand. If you remind me of something I will not get angry or offended[2], and usually the embarrassment of being reminded makes it stick better.

On a related note, if I seem to be transposing words, or using entirely the wrong word, or calling someone by the wrong name and not being aware of it. This is related to above. The filing system in my brain is only slightly better than hiring a monkey on PCP to organize the Library of Congress. And the more tired I am the less likely I am to notice my errors. Once again pointing out my errors, or asking for clarifications are fine and welcome."

[1] and yes, this is at least as painful for all involved as it seems like it would be, probably more.

[2]depressed and apologetic is more my MO for this.
