when it was current several years ago.
It has been replaced by the cardboard "Partner".
My Significant (or, as I prefer, Special) Other
has never 'co-habited' with me, lives in a different country,
visits me for a month or so at least three times a year.
He is my non-cohabiting, celibate end-of-life-partner.
We have many things 'in common',
but sexual congress is not one of them.
He is a Dead-Head. He has two Significant Others.
My surname is the same as that of The Grateful Dead's
great rhythm guitarist.
His other Significant Other (whom he hasn't seen for years
but talks with several times a week on the old-fashioned
landline telephone) has the same first name
as the G.D.'s brilliant lead guitarist with an Hispanic surname.
I think this is Otherly Significant.
