My cousin is a piano teacher and this is a conversation between her and a six year old student that she recently posted to Facebook. I repost it here with her permission.
Me: (to my six year old piano student). A TRI-cycle has three wheels, and a TRI-ad has three notes in it. What does "TRI" mean?
Isabella: Try means you never give up!
Got that folks?
TRI means you NEVER GIVE UP!!!!
