The rattle of the screw top of the bottle being opened just happened 15 seconds ago. It is Christmas Eve and I am in a room next to my girlfriends bedroom (we have separate bedrooms).
This noise tells me that she is just about to take a top up of Mr V. She drinks straight from the bottle. Maybe two swigs on neat Vodka. Sometimes it makes her gasp a little - it would. This is the next signal that she is proceeding as normal on her binge.
It is the clink of impending mess and of hell to come because after you've drunk a bottle and more of Vodka a day (sometimes she drinks the liter bottles) for 7 days or more you are messed up and so it your bedroom.
