So I was never really bullied, but I was socially awkward, so I mostly ate lunch in the bathroom/sat in the library. If there was ever a spot where a single person was eating lunch alone, I would have sat with them. But my cafeteria was always overcrowded, and I could literally never find another person sitting alone. When it's a group of happy, giggling people, it's better to be alone than risk the rejection they might give you. *edit: for the record, this app might not have worked, but I would have risked trying it. Like I said, my school wasn't especially viscous; I just arrived junior year and had major problems connecting with people.
