Teenagers are just having one issue with them,.which is the habit destruction. They are ready to remain inquisitive on any forms of thing they see. This does not mean they are foolish, buy are just still children who are still learning.
This is a statement which I learned from my dad as well. He never told me not to marry out off pity but his way of reacting with his children was quite different from other fathers.
You have truly learnt a lot from your dad.
