Cross about Computers

Another quote from Lucia (aged 3):

Lucia to Dad who is working on something on the computer so can't come and play a game with her: "You're making me cross!"
Dad: "Oh - well then you may need to go to the stairs to think about your attitude for a while because it's not good to get cross about such a little thing."
Lucia: "It's not a little thing - it's a big computer!"
