You say potato

Dietrich has a habit: He likes to sit in his stroller and say "aaaaaa." He says "aaaaa" as long as he can, and then he takes a breath and says "aaaaaa" again. When he does this at church, everyone says, "He's singing."

Yesterday I was in the rinok (outdoor market), waiting in line to buy cherries. Dietrich was "aaaaaaa"-ing. Another guy selling fruit looked down at my sweet, cherub-faced little bug and asked him, "Who are you swearing at?"
