Sure, I know more things, but forgotten others. I like to think the former outnumber the latter. Perhaps I'm wiser. Perhaps not.
But, for the most part, I still have the same thoughts as before, be they wonder, delight, dirty, sad. Hopefully I will express the correct ones at the proper times, but probably won't.
I found it fascinating when I realized that most others are in the same boat. The guy standing next to me at the bank might be 73 but he is obviously enthralled with the pretty teller behind the window, and I'm sure that if I told him a dirty joke, or even one that disparages someone's race, gender, or religion, we would both laugh because we are too old to care about political correctness, and besides, we are thinking like the teenagers we feel we are, anyway.
And we'll laugh without guilt because we understand that a joke can be funny and still not lower our respect of those that resemble the characters in our jokes, and I hope others are telling equally funny jokes with characters bearing a striking resemblance to myself.
