Learning the words

Moira went to Nana's house today

Over their day they decided to make dinner for Mommy and Daddy. One treat on the menu was "Ants on a log".

While preparing this dish, this following conversation happened......

Nana: Just put a couple on

Moira: How many is a couple?

Nana: More than 2

Moira: That's 3, where do you get these words? You talk funny like my Mommy.

Nana: Well I taught your mommy how to talk

Moira: Why'd you teach her funny words?
