Great piece, right here @dedicatedguy. I have really experienced this vicarious embarassment on so many levels. The line below which refers to close family or friends who spit something inappropriate too is a raw spot too....lolz
There is a situation in which the embarrassment of others is especially uncomfortable. For example, when it is someone from our group of friends or family who says something that seems out of place.
However, unlike your conclusion which talks about the observer and his or her insecurities, I do not feel such, at all. Rather i sympathize with the person who is goofing.
Thanks for sharing this mate, just an example of all the different approaches there can be regarding these types of subjects.
