What amazes me about any 'morning after' scenes on film or TV is not the fact that both people look like they just went to bed, instead of just waking up - it;s the fact that they usually share a kiss.
Now i don;t know about you, but here in the real world, my mouth feels like a baby dragon used it for a potty when i wake up, and the present Mrs Hughes confirms that my breath certainly contravenes 'dangerous gas' legislation - so how come no-one in fiction seems to suffer? Surely one or other of them must have snored with their mouth open and been appropriately 'malodourous' the next morning?
And that's before we get into razor rash, smudged make-up etc. ....
