Everything can be a topic of discussion
We said it before: things just hit different when you turn 40. Some items probably annoy you more and more over the years, but others might become fascinating to you, like the color of certain sponges or the rate at which the grass grows.
It might be weird to talk passionately about how quickly the grass grows for some people. But those of us who are over 40 know well that seemingly ordinary things can also be super interesting if you pay attention to them.
