I went to the nursery to take the nursery's money
Why did you take the nursery's money?
It's for the best. My dad is in huge debt.
It does look like you need the money but you cannot steal it. You will be arrested and have to return the money. It will be better to try to make the money somewhere else.
I have to save my dad. I don't care what you say.
You should help him with the debt by getting an extra job or help him with his spending or getting the entire family involved. Stealing from others would only invite more trouble to your dad.
