A recent survey by the Center for a New American Dream reports that when parents say no to a request, 60 percent of children keep nagging, on average, nine times after being told no. Ten percent of 12- and 13-year-olds even said that they nag their parents over 50 times. Even more troubling, 55 percent of the children surveyed said that their parents usually gave in. When you're friends with your children, they won't respect your power to say No! and mean it.
Sinker (baseball) In baseball, a sinker or sinking fastball is a type of fastball pitch which has significant downward and horizontal movement and is known for inducing ground balls. Pitchers who use the sinker tend to rely on it heavily and do not need to change pitch speeds as much as other pitchers do because the sinking action induces weak bat contact. Other pitchers normally change pitch speeds to achieve this effect. The sinker is much more often used by right-handed than left-handed pitchers.

This irrigation component keeps non-potable water from inadvertently entering the water supply through outlets of the irrigation system.
