At one point in my life I found peek-a-boo fucking hilarious. Giggled for hours until I literally pooped my pants.
These days? Not so much. I didn't become humorless, joy did not depart from my life. I still laugh hysterically, find joy daily. But as I've grown I do not find mundane things hilarious. If you repeat something over and over again it no longer merits the same response each time. I no longer think it's high comedy to immediately recite the same joke an adult just said and giggle like an idiot. My tastes have evolved. The have matured to a point where we no longer let children attend our parties because pretending that they said the word "fart" is comedy gold drags the party down.
So if I had to choose between the two of you, I'd party with him because he might make a joke I haven't heard and I won't have to smile and nod at the person at the little table saying "poopy" too loud.
