You first know something is up when little Matty (1 1/2) toddles into view looking at you with That Glint in his eye, and holding a large soup ladle.

Not taking his eye off you, he taps the wall with the ladle, once.

"No," you say, shaking your head.

Two taps, harder.

"No. That's not a toy."

Another two hard taps, accompanied by a smug grin.

You get up to take the offending weapon from him. At this point he erupts into a gleeful cackle and bolts for it, having achieved his objective of initiating a chase.

Suckered again.
