Imagine you're sat a table. The table is covered in an olive green table cloth and you notice the subtle vine pattern woven into it when you lift the folded cone of a napkin and shake it open onto your lap.

The table is nestled in the corner of a London Chinese restaurant and above it hangs a basket of fake fuchsias and an appealing picture of yellow lillies.

The others at the table are talking, smiling, laughing and you can turn around to chat to people on the next table who are also part of your group.

You have spent the last two hours at a nearby pub, clinking beer-filled mugs, throwing your head back to roar with laughter and slapping your thigh.
