For Arab speakers of English, differentiating between 'p' and 'b' is quite difficult since Arabic has no 'p' sound, so we may say 'p' as 'b' like banda instead of panda, bark instead of park or bin instead of pin. We don't have the "p" sound, we have only the "b" sound. If you say, "Don't park here, please", we may repeat it as, "Don't bark here, please":))))))))
