Right handed people often do not recognize that many things are designed to work well only for right handers. Here are a few examples: Most household equipment have buttons and controls that work better for right handed people When sitting at a dinner table, lefties have to be careful because they are always touching the elbow of the right handed person next to them Most public transport facilities are designed with right handed people in mind Most simple measuring equipment - rulers, tapes, measuring cups etc are designed for right handed people School desks (the ones that lift up for you to sit down) assume that the child will be right handed. The QWERTY keyboard works better for right handed people.
