Me, working at home, in the kitchen: Hey! I told you I had a call at 9.
SH: I know.
Me: But you are about to grind coffee! And the water is starting to boil! It's noisy!
SH: I have three minutes.
Me: No you don't! It's 8:59. My call starts in one minute.
SH: No it doesn't. It's 8:57. Look at the clock.
Me: Which clock?
SH: The one on the stove.
Me: That one isn't right. The clock on my computer is 8:59 and that's the one I have to go buy.
SH: But I had it all calibrated perfectly!
