Got called a Bi**ch by a 8 year old

The pools open but the waters freezing, I told the child I’ll give you 10 dollars to jump in the pool and he did it so 10 dollars was owed but I did not have a 10 dollar bill on me. I said I will get change later when we go out. Later at diner he’s sitting across the table from me, looks at me and says “you better give me my money before you leave”.

Now I know he didn’t actually say it but all I hear in my mind was you better have my money B******TCH
