"Aren't my gambling dad, my sick mom, my younger brother in school, and her broken self worth supporting?"
Worth it.
"I just supported hundreds of such broken women at the same time. Is that too much?"
Not excessive.
"It's reasonable for me to have a relationship while supporting you, right?"
Reasonable.
Then why do you think my purpose is not pure? Do you have to explain it clearly to me today?
You... Talk too much.
