human beings who believe, regardless of how old they become, that the entire world revolves around them, and thus, SUCK the time from anything you may be doing. Contraindications are usually avoidance, but bribery has been known to work in some circles. Relocation physical proximity is often the only cure once bitten; that, and blocking them from being able to send any kind of Ethernet, internet or dog catcher's net transmissions.
They are such Time Vampires - I can get nothing done when they are around.
