Where do parents draw the line between being concerned and being controlling?

Parents start to cross the line when they check their child's texts, look through their child's photos and not let their child go to fun things (eg: parties, sleepovers). Yes, if they sense some distress in their child they should try to find out whats wrong but not looking through their child's private life.

Concern is when u just want to know how your child is doing and whats happening in their lives. Controlling is when you want to intervene in everything your child does and you want to always know whats happening.

being controlled just means they want what's best for you being concered is because they love you and have your best interest at heart

When you become the person that they want you to be and steer away from the person YOU want to be.

It depends of the parents. Parents are human too, and to err is human. Try to talk it out with, them, explain what's important to you about whatever it is you want to do, and try to get them on your side. If they still say no, then I don't know.

Being a concerned parent is not letting your child do things that are a risk to the child. Being controlling is stopping them from doing harmless things, giving them no freedom to experience things for themselves and excessively checking up on their child

Concerned is making sure that you are okay, listening and being supportive. Controlling is disregarding your feelings and trying to take matters into their own hands.

Concerned is keeping the computer in the living/family room. Controlling is only allowing the child on the computer for an hour a day and you must be next to them while they are on the computer. You draw the line on your child's maturity. your child's common sense and child's age. Who they hang out with is another important factor. Also, another factor is your child's overall emotional and psychological development.

Depends on how much they love you. You need to show them you are responsible and good enough to make your own decisions.

In my opinion, if a child is old enough to understand reasoning (and to have a personal life), you shouldn't invade their personal life in a way you wouldn't with your spouse.
