How about munni key amman sounds ? Munni is now 45 year old her dad is 70, her mother is 60 , I don't know why munni kay abba realize that it was long time ago that munni was born and they should start using some other salutations for each other , like "jan a mun".
See "Munni k Abba" will always hold true, but "Jan e Mun" is not a guaranteed ...one should always play safe :)
