Reverse psychology

I just witnessed Lainey using reverse psychology on Jeff. She wanted to play with an umbrella in the house and Jeff told her that it was too big to open in the house and he didn't want her to poke herself with it. The convo went like this:

J- Lainey, that's daddy's golf umbrella and it's too big to play with in the house. And i dont want you to poke yourself with those sharp points. Let's put it away. 

L- but I would like to play with it. 

J- sorry baby, I said no.

L- okay... but I don't know how to open it. Do you?

J- yes, I know how to open it.

L- okay well..... I don't so would you care to show me?

J- not really, no.

L- because you don't know how?

J- *sigh* let's just put it away please.
