Son: Mommy can you give me two dollars?
Mom: I gave you them three hours ago, you will buy an ice-cream, aren't you?
Son: No mommy, no. This time, I will give these two dollars to old man.
Mom: Oh my helpful son, I just thought you will buy an ice-cream again... I'm so proud...

Mom gives two dollars to her Son.

Mom: So, where's that old man?
Son: He is selling ice-cream at that house.
