People arguing on here that know each other IRL

I wonder if two people have ever unknowingly argued on this platform, or had any meaningful discussion with each other anonymously, and turns out knew each other in real life.

After thinking about it, some smaller niche communities much more likely to happen, especially if you also do that hobby in person. But I wonder if it happens on a bigger scale

I just find it funny thinking about some insulting argument you have and turns out it’s like Bob from accounting you work with and you’ll never ever know.
