I grew up with Maddy as a regular presence within our house. He was one of Chris's best friends since we had moved to Colorado, when they were in 2nd grade. My first memory with him was when he had invited my brother and I both to his house to hang out, even though I was two years older. Even then normalized social boundaries never mattered to him; he was full of life and was so generous with his kindness.
We played Magic the Gathering for many hours. I remember getting beaten quite a few times, dang future engineers and their intellect, but we all had a fantastic day. Then after lunch he took us into the garage to show us another of his hobbies. He showed us the jewelry he had been working on. It wasn't a normal elementary schooler's jewelry either (e.g., friendship bracelets and plastic beads). No it was gold. His grandfather had shown him how to make necklaces into chains and other techniques. I was awed by this. To this day I can't get over how cool that was.
There are many other stories of shenanigans throughout the years, but this story shows how I always saw Maddy. Exuberant, gregarious and nuanced, with an incredible ability to make everyone smile/ laugh when he was in the room. <3
