1. The best thing about spending time with your family is a heart-to-heart talk and making every member feel like a part of something special.
2. The worst thing is when parents let their children do whatever they want. Besides, parents shouldn't yell at the kids or beat them.
3. I don't think that parents should be strict with their children, but it's a difficult question... It all depends on a child's character. I believe that parents should raise their children with love more that strictness.
4. I think that parents should be friends with kids. Parents and children should respect each other and care about and trust each other. But this friendship should not mean “nobody is in charge”. There should be some rules and standards and it is up to parents to be older and wiser.
