I'm happy giving large amounts of money to my mom and helping her with paperwork
Do you enjoy helping your mom out?
It makes me feel really good when I help my mom with paperwork.
You're such a helpful son!  It's good that helping your family out makes you feel happy.  I'm sure your mother appreciates it!
She should just let me do whatever, I need to enjoy my life.
I thought you were doing this of your own free will though? Nevertheless, it's nice to see you help out your mom when you can.
