“Abby, who took the potato chip bag?”
“I Don’t Know”
Destiny, who took the potato chip bag?”
“Nobody, Grandma!” (suspicious statement)
“Hannah, did you take the potato chip bag?”
“No, I didn’t do it, Somebody did” (skipping away, singing Jingle Bells)
So, there’s my answer ::: First I Don’t Know took the chips; then for some reason Nobody got a hold of them; and finally for some unknown reason Somebody took them far far away ::: mystery remains unsolved.
