oh nothing much

my ma asked me a question today and i replied oh, nothing much...
and she remembered this book i used to read as a little kid.
this little boy couldnt watch tv one day. so he resorted to playing with cardboard boxes, trying to entertain himself. his mother kept checking up on him. asking him what he was doing. and his reply was to say nothing much.
so funny. she remembered the book. i remember it. i was purple and green. and the tv was big.
