Everyone is on the internet these days. Everyone has an account on everything, which means even the biggest celebrities and all of the experts out there have social media accounts. There is no saying who is going to see what you post so it's best to know who you're talking to before making any big accusations or statements. Not knowing this might just put you in a position of trying to correct an expert, which is embarrassing, but it happens surprisingly often.

Reddit's /r/dontyouknowwhoiam is a subreddit that features hundreds of accounts of people saying things and then immediately finding out they were talking to the wrong person. In most cases, someone asking the question "Don't you know who I am?" is pretentious, but in these cases, it is totally warranted. Here are just 15 times someone did not realize who they were talking to, and it gets super awkward.
