Right, am just finishing my balikbayan box which I'm sending today and I have written a card just for Viva, but I also have another one for her mum, sister and Viva. Now I'm not sure what to call her mum when I write it in the card? Just Mrs. ******* (her surname)? But it seems maybe a bit too formal? I have met her by the way if that makes any difference?! What's the right protocol here?!
Any help greatly appreciated!
