The living room and my father 's bedroom were not only adjacent , but were separated by only a curtain to keep out the light . We children were constantly admonished to " keep the noise down " ; but as far as we could tell , most of the noise was coming from the posterior of my father . He farted often and with an authoritative loudness . His most - oft repeated fart was what we kids called the " motor boat " .
