You two get very different kinds of email mixes, and that's all there is to
this.  And someone who uses Emacs to read email is by definition too geeky
to be representative of anyone in the real world <wink>.

There more kinds of email users in heaven and earth than are dreamt of in
your classifier, Bill.  I don't get an email mix anything like my sisters
get either, except for the spam.  I know they got a lot more HTML ham than I
get, and sounds like Ryan gets even more than they do.  So it goes -- people
are different.
