I was reminded of this beaut thought by Carol Zampa's latest blog post:
Piglet sidled up to Pooh from behind. "Pooh!" he whispered. "Yes, Piglet?" "Nothing," said Piglet, taking Pooh's paw. "I just wanted to be sure of you." ~A.A. Milne
But maybe it is after all possible only in Winnie the Pooh. Or with dogs.
