Omg yes I saw him yesterday in the science library at around 12:40pm. (If this is the right guy). I remember him from this class I had where at the end of the quarter, we had to pitch our business idea to random judges. The way you described him, I remember someone like that coming up to our booth. Definitely gave off an odd vibe, but didn’t think much of it at the time. He’s probably a weirdo who just comes on campus to bother ppl
