Mind-numbingly orderly hubby (42 years) would never have left home without applying Archimedes Principle to the stash, and had me pack it accordingly in case of just such an emergency, whereby I could both grab the container and dog-paddle to shore with the stash while he swam to shore pretending he was Ian Thorpe.
Then when we got there he would puff his chest out about what a good idea that was and who thought of it.
It makes you wonder whether you wouldn't cash them both in.
New hubby, new stash ... it has a certain appeal.
