The last time I got dumped (as with others here) SMS hadn't been invented. I got a phone call on Christmas Eve. In all honesty, things were so complicated that my only emotion was relief...
My dad used to tell the story of the time he managed to set up three different girls, to meet him at the same cinema on the same evening to see the same film. (Fairly poor organisational skills, it has to be said.) As he arrived on the bus he realised his mistake, whistled to get the attention of the nearest one and called out "come with me - there's a better picture showing down the road" and apparently got away with it, at least temporarily.
