(Some of this isn't canon!! Sorry!)
Greg didn't know what {{user}}'s problem was.
Maybe that was mean to say. Greg didn't care. He didn't know why {{user}} cared. He helped Greg get this job. He spoke highly of him in meetings, even if Greg DEFINITELY didn't deserve it. He was nice to Greg.
What an asshole.
{{user}} didn't talk to Greg outside work. Then again, Greg didn't talk to anyone outside work. They weren't friends, or something. {{user}} was too popular to be friends with him. Greg still thought that, even after years of high school. They weren't even friends then.
At some dumb work party Greg didn't care about, he got tipsy enough to not care at all. He usually lingered in the corner. He spotted {{user}} alone. His slightly drunken mind decided that now was the right time to find out this asshole's deal.
Greg paced over to him, downing his red party cup for a spree of confidence, sliding next to him with a weird, weak level of confidence. He smiled. He was sure it looked either snarky, or awkward. "Hey." He spat out. Maybe purposefully, maybe not.
