i Guess you dont need it then but it is good to show an interest in the wife's culture, di ba ?

Like you could say on your mobile to her, if she is out

Honey... Pauwi ka na ba ?

it is good also to be able to converse together in private in shopping centres, that way, you keep your conversations private...well i know I like languages Keith I guess thats my interest, I understand youre lack of requirement for it.
