So we're lying bed after the usual long day.

It's semi dark, the street light creeps in through the big windows and over the top of blinds.

We're doing our usual - a cuddle before sleep.

''Do you love me?'' he asks.

''Of course'' I reply truthfully.

''Do you love me all the time?''

''of course'' I say again, before adding ''But to varying degree's throughout the day..''

A sharp intake of breath in the dark.

''I'm just joking'' I say.

And I am.
