Here is a topical one to be going on with.
Clues:- (you can't complain about the lack of clues this time)
Some of us have these, Some of us don't
Some of us tell all, some don't
Some of us fake them, some don't
Some of us chat about them, some don't
Some of us wish they weren't (probably most)
Some of us don't care
Once, for some they were useful
Some consider them decorative (I do
)
Those that have may wish they hadn't, those without may wish they had.
I am pushing my luck.
