A friend advised that when choosing someone to be romantically involved with, it's good to estimate how long it would take before you were out of topics to talk about - if you had the misfortune to end up stranded on a deserted island.
So I quickly did a run-through of my male acquaintances and came up with a list ranging from 30 seconds to a few months.
One stood out though. He could easily spend a whole year making just one long story short....and that's without me interrupting. Crazy about that guy!
