I like khwateen,sadzz and sazzie answers.If you are a muslim or you can say if you have different culture and different mind set of rules in your house then teach your children and make them confident enough that they don t sneak out and do these things behind you. Kids learn what their parents want to learn instead of beating, hurting or forcing rules we should teach them and explain them everything why we are not doing that.And we should answer all their curious mind questions so they know what is religion and what is the difference between some cultures if we want to follow our religion.
