Bad language in a bike shop may be the Norm in that environment...but it is not civil...it is merely the norm...One of the things that seems to allow bad behaviour is the rather facile excuse that it is "the norm" in certain situations. When are we going to realize that we cannot allow disrespect for others on the basis that it is a "norm" in some situations. as for a definition of civility....that is another one of those feeble thoughts of the "i Can't do it because I don"t know what it is variety" . Do we need a precise definition of common sense as well ?
