Gosh, what a quandry! If they haven't contacted you tomorrow, I'd go door-to-door on his street asking if anyone knows where the little boy named Mark, or who looks like such-and-such - lives.

But I am pretty outgoing. Could you call the local school, and ask if they have a phone number for him, or give him a note to call you right away?

Miss Hoppy and I will be keeping our fingers (or toes) crossed 'til we hear from you! Poor you! Poor Bunny and Shadow and Mark, too!
