I'm so, so incredibly sad to hear that Bob has moved on. He lived up to (and exceeded) all the wonderful words that are already written here. I would just like to add that he was a great teacher. I'll never forget the time I came home from high school with Austin, and joined in on an Unruh family dinner. I remember being a little nervous, because we didn't really spend much time upstairs with his parents. We mostly stayed in the basement with some pizza, ping pong and video games - like a couple of ninja turtles.
Before we all sat at the kitchen island to eat, I washed my hands in the kitchen sink just trying to prove that I was actually pretty civilized. I remember I burned my hand on the scalding hot water that came out. "Ah!", I said while shaking my hand in the air, more surprised at how efficient their water heater was than the pain it caused. I think Kristy asked if I was okay, but Bob gave a wry smile and jumped on the opportunity to say: "Looks like someone needs the ole hot-and-cold lesson", a statement which I distinctly remember made Austin and Kristy groan. One of them said "oh god", and the other said "heeere we go." If Kloe was there, I imagine her reaction would have been the same, maybe adding in an eye-roll.
Figuring this must be some kind of Unruh house secret, I waited patiently while Bob stood up and walked to the sink. It took about 2 seconds to realize that he was about to give an extremely sarcastic, in-depth lesson of what the words 'hot' and 'cold' meant, and how to identify it on a sink. I was probably about 16 years old, and just so embarrassed that I was essentially getting roasted by my friend's dad for burning my hand, and also couldn't believe how committed he was to this little bit about hot and cold water. It goes without saying that no one came to my rescue, I think Austin was dying of laughter at this point. I assured Bob that I already knew all of this basic information, for quite a number of years now. And I believe he said something like "Really? If you say so!"
It was a great lesson, not necessarily in thermodynamics... mostly about sarcasm and banter... but more than anything, it really made me feel like one of the family. The hot and cold lesson was a rite-of-passage, I guess. It's just one of a whole library of moments with Bob and the Unruhs, that I'll carry with me my whole life. Thank you, Bob.
Sending all the love I have to give to the Unruh family,
Noah
