Double beds are a bad idea.
Everyone knows familiarity breeds contempt,
But not everyone realises that double beds breed contempt AND children.
Yes, I do believe in a single bed policy.
Double beds for married folk is a total fallacy.

Do we really need double beds?
They're all elbows and knees and farts.
Why can't we sleep apart?
Meet up in the morning and smugly tell each other how well you slept.
Maybe arrange to have a twenty minute cuddle in a neutral bed.

See, no double bed no sleepless nights.
No simmering hostility because of a careless knee,
No cold war because of cold feet,
No lifelong bitterness because of blanket stealing.
And no ill-feeling because "you're taking more space than me!"
