I won five million in the lottery, and I told my mom immediately.

My mom said, "Don't make it public, save it first, and spend it slowly."
I followed her advice.
A month later, my mom suddenly bought a Porsche.
I asked her where the money came from.
She said, "I also won five million, just a day later than you."
I said, "Then why didn't you tell me?"
She said, "I'm afraid you'll ask to borrow money from me."
