I felt good interacting with him. Often, it was from a distance and just me and my thoughts, but it felt good to think about conversations past. His tone of voice had a sense of purpose as much as it could have humor, and it never judged. I remember meeting him as a high schooler for the first time, I barely spoke, but sent him note cards right after, more than a couple, all at once, because I felt like it. Thiruvengadam Lakshman Sankar or thatha* as he let me call him affected me.
