Any outing with two people can be considered a first date. For that reason, avoid the following:
Movies: The whole point of going out on a date is to talk and get to know each other. The whole point of going to a movie is to keep your mouth shut and watch the screen. Of course, you then have ample fodder to discuss afterwards but the setting (though it is dark) doesn’t lend itself to getting to know someone. No one past the age of 18 makes out in movie theatres anyway.
Concerts: Though you may love Metallica and she thinks they’re righteous, once again, the whole arena scenario comes into play. The shouting, the long line for the bathroom, the elbow in the ribs, are not romantic nor are they fun. Hit the mosh pit with your best friend, not your date.
Parties: Attending a party requires knowing someone hosting the event. Perhaps it’s you, or maybe your date, or even both of you who knows the giver. Regardless, she will smuggled off by her friends to find out what’s going on between the two of you. If you know the person throwing the party, you have the tedious responsibility of introducing her to everyone and then dealing with the small talk. This is not enjoyable for anyone.
Your first date should be thought out if you want a second date. Don’t stress yourself out over mundane details -- just plan appropriately, have a back-up plan, and be flexible. If you end up at the end of the night fidgeting on her doorstep, you’ve done something right.
