You can not stop him, i need to stop himself. Otherwise he will stop for a month and continue after that.
One time i said to my dad to make a statement, in which he wrote not to drink. with his signature.
We had a bet and i had won this, so he had to stop drinking.
Next day he laugh and said that's not my handwriting.
My meaning is paji that someone can one stop with his heart, not by you, me.
