Brother! Lol, yea I know I would grow to be overprotective about my children at some points so I forgive my parents too!
I think I have gotten my mum to believe in me in some way, I am not sure about my dad though. Because he is always the least overprotective. Was just surprised why he was like that recently.
Probably getting insecure about you doing your things on your own terms? Use your mum to your advantage and ask her if she can put some sense into him. Whatever works for you xD
