I am the last person on earth to make fun of anyone with any kind of disability. But both the people I am about to write about have obviously long since died and it is highly unlikely that anyone close to them should read this.
The time would be around the late 1930s. The shop on DaveR,s photo on the left traded under the name of "Ida Turnbull." ladies outfitters, run by Ida Turnbull. Unfortunately for her she suffered from a terrible twitch which forced her to constantly and suddenly fling her head and neck to one side virtually every half minute or so. You must admire her, she was also the main star in the Colwyn Bay light opera society, she always took the lead female roll. Apparently she had the voice of an angel, and when she had a particularly long note to sing, not a sign of the twitch. The moment she closed her mouth she would erupt into two or three strong twitches.
Right next door down Rhos Road was a shoe shop. Run by a man, name unknown to me. But his nickname to everyone, adults and kids, was "nodder." As you will guess he had an uncontroled need to nod his head constantly, the shop was always referred to as Nodders.
A strange coincidence that they were neighbours. They must have both had strong characters. In those less tolerant days they must both have suffered torment, if only from kids.
