I'm going to bully an old lady who stole my avocados
How did the old lady steal your avocados?
She asked me to pay her back for getting them from the store for me.
You are responsible for paying for the avocados that she bought for you. Bullying her is wrong-headed logic when she did nothing wrong. Pay her what you owe and don't bother her.
I don't want to pay her. I'm going to teach that old lady a lesson and publicly shame her with all my friends.
It is not going to go well to bully the old lady. The truth will come out about you owing her money and people will turn on you.
