You high tech guys amaze me. I can't even figure out what those two buttons do on my wife's car keys. She told me when she presses one a robot drone changes the oil and when she presses the other a different robot rotates the tires. I didn't want her to think I didn't believe her so when she was in the house I tried the button that was supposed to change the oil. It didn't work. All it did was lock the car doors. I pressed it again and the doors locked again but the horn beeped too. She ran out of the house wondering why I was beeping. I told her I was trying to change the oil with that fancy button on her key. She just smiled and said it must not be working right and walked back in the house. The lesson I learned about technology that day is to never depend on it because it always malfunctions.
