Mother knows best
My mother used to say in the shop "Do you have something with one button? Just one on/off switch?"
Many, many moons ago I did not understand the sentiment and was almost embarrassed. Now, I am proud of her asking and sticking to the simple truth.
And now, today, does this technology of buttons, devices and impossible combinations actually make us happy? I guess that a simple working on/off switch would be a significant improvement.
