I don't have one. A perfect first date only exist in fairytale.
Mostly, what peoples will have in mind about the perfect first date are flowers, movies, beach, ice-cream, candlelight dinner or bla bla bla romantic stuff.
Reality is, it could be anything.
Even if you have to wait 1/2 hour for your date to arrive.
Even if you have to sweat in no-air-conditioning-bus.
Even if you don't have anything to say.
Even if you are not in your best clothes.
No one can tell you it is perfect if you don't feel it yourself.
So, theater anyone?
