I had two "I am old" moments recently.
1.) We started carrying Mexican Coke in glass bottles at work. Everyone there knows they're one of my favorite things. So, I'm walking down the hall when a younger associate passes me carrying one of the bottles. She kinda holds the bottle "How am I supposed to open this?". I tell her I've got a bottle opener in my office - so, we step down to my office and I hand her the bottle opener. It's nothing fancy, just one of those with the bottle opener on one end, the can punch on the other, and a magnet in the middle. She holds out her hand, and I lay the bottle opener in her palm.... she looks down at it, then looks at me "I don't know how to use this." And she's not stupid or anything - she's just never had to use a bottle opener. Makes me sad.
The second moment was when I was in the break room with a co-worker playing Mario vs. Luigi. One of us had died via bob-omb and one of us said the phrase "Some days you just can't get rid of a bomb." Of course, we broke out laughing and another, younger, co-worker didn't get the joke. I said it was a quote from the greatest movie of all time by the greatest actor of all time. The other co-worker asked who - and I said Adam West. They asked "The mayor on Family Guy?"
