Dear, erm, ...
Evidently, some people - or companies - struggle with how to address partners who are not married.
A few days ago, myself and the other 'arf received a letter addressed to, wait for it ...
Ms. and Mr. Janine and John Booth and Leach
I don't think I have ever seen a more absurd and ungainly attempt to do the simple matter of addressing an envelope. Personally, I can not see for the life of me what is wrong with the straightforward:
Janine Booth and John Leach
... but I guess that the combination of different surnames and the seemingly-unshakeable insistence on totally unnecessary titles led them to this appalling mouthful.
It would be interesting to know whether a computer or a human being is responsible.
