I don't deliberately keep a blind over my eyes regarding changes in my world but I must confess that many changes slip by me easily. For example, I have recently become aware of fist bumps as a replacement for handshakes.
I regard this as highly symbolic of the times in which we live. In this age of discord and discontent, a clenched fist encounter replaces the handshake. After all, a handshake pulls you closer to another person, kind of like a mini-hug with the hands. As far as I can tell, today's society regards that at a weakness and the fist bump as a stronger, more aggressive reaction when dealing with another person.
I don't buy it.
