@mudasobwa yes, I see your point and generally agree. But I believe that uniting with others through pushing your bubble boundaries gradually is a more viable strategy than doing so through self persuasion that tolerating farts in your face (or anything perceived as ones) is for your own good and it is better to take a deep breath to suppress your reluctance.
For some people extending the bubble to two persons in is a challenge. In this sense, social networks actually do work.
