Maybe I'm wrong here, but it seems to me that there is a distinct difference in respect for boundaries between the right and left......personal, physical, and emotional. The right are pretty much a leave me alone, get out of my face type.....the left is a "Hey there! Look over here! Yooooo Hooooo!!" all the while doing whatever it takes to disrupt.
I can picture standing along the beach somewhere looking at the setting sun, listening to the slap of the waves.....and have the above pictured abomination walk between me and the water, yammering on it's cell in a loud whiny voice. Kinda ruins the moment, you know?
