No Good Night?

For months now, part of the baby's good night routine involves me reading Good Night Moon. It hits me after the 235th reading - why doesn't the little bunny say goodnight to the telephone? He says good night to everything mentioned in the first half of the story except the phone. Is there something wrong with the phone? Is it not permitted to leave the little bunny? I want answers since this problem has been keeping me up at night.
