I agree with it because the parents are the exact visual of the teens in their everyday scene.

Yes, and you know what? teens whose parents smoke tend to smoke also, while kids whose parents regularly exercise tend to exercise as well.

In a following gender lines , I think it is most common that boys emulate their father, while girls are more likely to model their mother's behavior.

in speaking of  influences, the parents must be aware that they must be careful of everything they must do. so that their teens can trudge in the right path , they must be on the right lane of life.

parents have big impact on their children. what or how they become when they grow up reflects on their parents.

"the apple never falls very far from the tree".

Kids will follow by example and if parents provide a poor example, then their kids will grow up to be like them.
