When listening to someone, change your gaze from one eye to the other and back. Do not stare at one eye. To get them to stop talking, stare at their mouths or at a spot on their foreheads right above their nose and eyebrows. – Waldo Weyeris
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
