bertie why do you bound ?who spoke so​

Answer 1

Answer:

Sappleton's youngest brother, Ronnie, kept signing "Bertie, why do you bound? " to tease Mrs. Sappleton as she said that it got on her nerves.

Answer 2

"Bertie, why do you bound" is a line from a song from around 1909 called Bertie the bounder. You can listen to a sample of it at that link. Bounder is an old fashioned word for a "dishonourable man" (Oxford English Dictionary, Kindle Edition). As Glasguensis says, to bound also means to jump or leap about.
