Wacky Wednesday

When you were younger did you ever read the book Wacky Wednesday?? It was by Dr. Suess I believe, and I absolutely loved it. It reminds me that there is something wacky everyday we just need to observe it. Something extremely random and wacky question today is: Why is it the "social norm" to get married? I honestly will get married when I am older, and I believe that marriage is important but who started it? What was the original point of it? Do any of you ever have weird thoughts like this??
