Sometimes, dh & myself will spell out certain words if we do not want to let the kids hear. Did not know that Shan has already grow up & she already know some spelling.

Me talking to dh: (not wanting to disappoint the kids if we did not go) Wan to go Z.O.O (Sp) later?
Shan sitting beside: Z.O.O ZOO?!! Yeh, we are going Zoo!

Oops! Eventually, we did not go Zoo also.
