Wrong, Ted called me. The issue of 3133 and 1839 being paired or not 
actually didn't even come up in our conversation since there was so much 
else of interest to discuss. I didn't sleep all night thinking of the 
exciting things we discussed, but I guess I'm a bit obsessed with this 
subject. It was in a separate e-mail in which I answered his query about 
the wording error on his website, something you posted you had done some 
time ago. Obviously this wording was a leftover from an earlier time 
when a pairing was suspected.

The proximity I was referring to was the Moroccan/Algerian desert, and 
the time is the same short period that you have been involved in 
meteorites. I have seen the plot on the CV mixing line for both 
meteorites and they are darn close. In fact, certain select isotope runs 
virtually overlap. However, I would welcome the first CO metachondrite 
to my collection!

The "official" part was obviously meant to refer to my website only, 
that is clear in my statement, and does not infer any pedigree from 
NomCom or anyone else. I have no idea where Aziz got this gift from; 
perhaps he acquired it from Ron Farrell in care of his partner Terry 
Boswell. Perhaps it is a piece of the original rock that he might have 
acquired from the Russians or Japanese. Perhaps a new pairing yet to be 
officially confirmed. I am not so rude as to question his generosity 
like you seem to want me to do. If you don't like which photos I use on 
my website to represent a particular meteorite, then may I invite you to 
avoid any confusion in your mind and not visit meteoritestudies.com in 
the future.

You are special Adam, don't let anyone affect your self esteem by 
calling you bad names. Just keep saying to yourself - sticks and stones 
may break my bones but words will never hurt me.

Till later,
David
