We've all had the embarrassing experience of having a fly or some other unknown bug fly in our face. While that in itself isn't embarrassing, our innate reaction is: we freak out, swatting rapidly and trying to get away from something we can't see, otherwise acting like a crazy person.
While our reaction to flies may be awkward, that is only because flies themselves are awkward. There aren't many animals dumb enough yet agile enough to constantly put themselves in harm's way for no benefit only to escape death by millimeters. Flies have an extremely short attention span, so their thought process is usually, "see food, get food, see danger, avoid danger, see food, get food, see danger, avoid danger," in a never-ending cycle. This is why flies often land directly on the same spot they were when you swatted at them.
This might seem like a dumb connection to make, but it can be a good reflection on our social personalities. Just because something is awkward for us doesn't mean we need to let it ruin the experience, because it is likely awkward for many other people as well.
Everyone makes mistakes and gets into uncomfortable situations, and our ability to make light of our interactions (especially negative ones) is what makes life worth living.
Embarrassing situations are also often worse if you let it ruin the moment. When something awkward happens, it is best to smile and push through it, because that usually let's everyone let go of it faster. It's life; you just have to live it.
Life goes on and doesn't stop for anyone, not even a fly. So, remember that next time something awkward happens. Chances are that nobody is going to remember it anyway.
