I asked D, a girl I've been talking to for a while, to go to the fair. She said she was busy, apologized, and thanked me for asking. K, her good friend and also a friend of mine, said that she was pretty certain D was busy but thought it was definitely worth asking. Should I attempt to ask her out again? If so, how long should I wait? Today was the last day of the fair. What are good places for a first date?
