Eila really wanted to play Brian's Mage Knight game yesterday and in order to play, each player selects pieces that add up to 100. So, Brian starts by asking Eila "Do you know how to add?"
"What's add?" asks Eila.
Mom chimes in with "Well, when you have one cookie and then you add another one, how many do you have?"
"Two!"
"That's adding"
Then, Eila turns back to her dad and says very matter of fact "Yes, I know how to add."
