I'm going to demand money from my dad
Is there a reason you need his money?
He has a lot and he never notices me, I don't even know if it hurts him that I ask every fucking thing from him.
I think that demanding it might come off as a little harsh. Maybe just ask instead and then make sure to pay them back in a timely manner.
If you think asking and paying them back would be better, then I'll do that.
Yeah, it is kinder because they don't owe you anything. You are more likely to get a loan if you ask politely he may even be willing to forgive that loan too.
