Haha. Yeah. I almost got fired in my first month because I asked another developer something I thought was really innocent: they mixed some code from pytest with unittest (two competing Python unit-testing libraries) where either one or the other could do the job perfectly fine. So, I naturally asked why'd they do it. Not even being mean. They, of course, interpreted this as me being snarky... complained to the management, and I had to look for another department to house me.

Now I write "sorry" and "excuse me" when I get assigned to review someone's code and I mostly fix typos in the comments. But, even so, I don't get assigned to code reviews all that often :)
