#1 They want to get to know you. This is the most basic necessity of them all. It is the sole reason why they agreed to the date in the first place. No matter what happens at the end of the night, the date is designed to make you feel comfortable around each other enough so that you can both progress to a higher level of intimacy.
#2 They want to have fun. Although it’s necessary to talk about each other while on the date, there’s no rule saying that you can’t have fun while doing so. Even if you’re just having dinner, you can still have fun just by talking about the things that make you laugh and smile. If you’re on an active date like a hiking trip, a bowling alley or dance club, you should make sure that your date likes the activity and that they’re not bored.
