You Entertain Each Other
It’s a cliché because it’s true: If someone can make you laugh on a first date, it’s a good sign.
But what about all the subsequent dates? What about the rest of your life? Why is the first date the only instance in which this is important? Wouldn’t it be great if your lover could always keep you entertained? If you share a sense of humor, you can probably make this happen. In that way, every single day of the rest of your lives can be, to some degree, just like your first date.
Doesn’t that sound good?
