I think I am going to assist my sister with buying a boyfriend.
It may not be a great idea for you to help your sister purchase a boyfriend.
Well, I think she has a right to have a boyfriend. She can't attract men.
Buying people is wrong. It's no better for women to buy men than it is for men to buy women. People shouldn't own people.
How could I own her then?
You do not own her. It is impossible for a person to own another person nowadays where we live. You should just help your sister find a date instead, the normal way!
