Walking on the Kerbside
In days gone by, a gentleman would walk on the outside of the
pavement to protect the lady from the risks of the road and the
perils of the gutter.
Today, a man should still walk on the kerbside of the street. If, however, a woman naturally falls in step on the kerbside and seems comfortable with it, then it would be clumsy for him to start dodging around her to try and walk on the outside.
