“I think you are missing the point. The point isn’t to “have a good time.”
I respectfully disagree. The point of a first date is NOT to make wedding plans – it is to see if two people are sufficiently comfortable with each other to enjoy spending an amount of time together (e.g. have a good time together). I think you and I are not semantically on the same page. Perhaps what you mean by “good time” and what I do, are two very different things. Why on earth would ANYONE want to go out with someone more than once, if they had a bad time? First meetings are crucial in that two people have a chance to see the potential for them to want to spend more time together. If that first time ends really badly for one or both of them, a second meeting will probably not ensue. That IS tachlis.
