Someone you've been amazingly fond of for some time will suddenly let you know that the feelings are extremely mutual. What should you do about it? Well, for starters, pick up your jaw and let yourself grin. Saying something appropriate wouldn't hurt, either: something along the lines of 'me too,' for example. You might also think of where to have dinner tonight. You'll need to keep up your strength if you're going to keep someone this startling entertained.
