If you were going to ask someone to marry you, how would you do it (or how did you do it if you already have)? Would you plan a Big Special Thing to surprise them, or would you keep it simple?
We'd watched Gilmore Girls season one together. When Max asks her to marry him, Lorelei says that they can't get married just to stop an argument. That there should be a thousand yellow daises, and a horse, though she wasn't sure what the horse was doing there. When we watched the scene, my girlfriend said emphatically, "Exactly!"
So I called around to the places no more than an hour's drive from our house that offered horseback rides by the hour. Did any of them have a daisy meadow nearby? In fact, one did. So my plan was to take her out for a ride, and get the guide to pause in the daisy meadow, and propose to her there. At the time, I figured the answer was certain to be yes.
Of course, then she dumped me. So apparently, there was a signal somewhere I missed.
