When was the last time that you did something that made you cringe internally? If you go out in public and interact with other people on a regular basis, the likelihood is it was probably recent. Life is hard enough as it is, but we often make it harder on ourselves.
A great example of this is embarrassment. The many untold rules of society combined with the quirks of human psychology mean that we can often find ourselves in awkward situations when we've objectively done nothing wrong. This has been highlighted in a humiliating thread by @444molls, which asked Twitter about all the situations we find awkward when in reality, they're 100% normal.
With people citing everything from using the restroom to saying goodbye, one thing becomes clear: we spend a lot of time being really bad at feeling OK. Prepare for a lot of involuntary shuddering reading these.
