He was an old friend who stood up for me in school when I was facing harassment. He had a tough persona, but he spoke softly to me and was gentle with me. That was in 2006. I messaged him on Facebook a month ago, nothing too detailed, just asking him if he was at [school] in 2006. To be specific, the exact message was “hey, were you ever at [school I went to] in 2006?”. I have a picture of my face as my profile picture, and my intention was just to re-connect with old friends or maybe to just thank him for what he did. That day, I was being harassed so badly that I was in tears. I’d been bullied a lot, and he was someone I looked up to. Today, his profile in my Chats list just says “Facebook user” and how he’s not available on messenger. My sister can’t find him on Facebook either.
