Can the strength of family bonds be measured by something other than time spent together?

Yes, it could also be measured by how the family treats each other. If the family members are more distant or worse, abusive, then the family bonds are weak. But if the family is loving and considerate of one another and respect each other, the familial bond is stronger and healthier.

absolutely can relationships with family and friends are not just based on the time spent together it's also the kindness and the way we treat each other out of respect or not.

no since you have to teach children some things there parents wouldn't like in order for them to be able to have a good education
