Bashful Bob and Doleful Dorinda by Margaret Atwood
I swear this was the most horrible children's book I've ever read!
Having been accidentally abandoned in a shoe store as an infant, I was prepared to like Bashful Bob and Doleful Dorinda.
Bashful Bob was accidentally abandoned outside a beauty parlour by his mother and is subsequently raised by dogs. He's a little shy around humans as a result. Doleful Dorinda is raised by abusive distant relatives after her parents disappear in an accident. They meet, Dorinda teaches Bob to speak, and they rehabilitate a buffalo who thinks he's a begonia. After this hits the news both sets of parents show up and reclaim their children.
Add in PAINFUL alliteration and I wanted to vomit ... or "bomit" as Atwood would have written to keep the flow going.
