show me the money

one of these days I will remember to put cash in my purse immediately after taking it out of my pocket...
the kid: look, mommy! I have lots of dollars!
me: those are my dollars that need to go back in my purse.
the kid: we don't need to do that. we can take them to the store and buy another controller for the wii.
me: if we do that, we might not have enough money to buy chicken and fries the next time you want them.
the kid: that's okay. I'm strong enough for no chicken and fries.
me: no chicken and fries? ever?!
the kid: (shocked look) well, maybe we can put these dollars in my piggy bank instead.
me: maybe you can put one of them in your bank and the rest can go back into my purse.
the kid: okay. can I keep this one? (holds up a twenty)
me: (snatching the twenty) no, but you can have this one. (handing him a one)
the kid: I like the other one better.
