sometimes a house is shared because the two of you get along and bills are cheaper when halved

Absolutely –– been there, done that, too. Sorry if I seemed to imply otherwise. My late husband Pat & I shared our house with a female friend for that reason, though I'm sure some people were wondering what was up with that.

Buchanan & King, OTOH, were widely known at least in DC at that time to be a pair of "nancy boys" & everything known about them today supports that conclusion.
