During my childhood, my mother wanted us to talk more Urdu than Pahari. Whenever we had to talk to people using the word 'aap', we always tried not to laugh, because 'aap' is the word for 'monkey' in Dutch.
(thinking about the Pakistani word 'apa' used for sister, that would be funny for any child growing up in Holland, a reminder of 'aap', the 'monkey' word)
