Maple calling

So Appa n I were out shopping this evening... Suddenly there is cacophony. A millisecond later I realize that it's coming from Appa's pocket. It's his cell phone resounding a ridiculously high volume. He grabs it and hands it over to me (he can't read who's calling without his glasses). An instant before I pick it up I glance at the screen. It says "Maple calling". I double-check the screen looking at it dubiously as I prepare to answer the call. Who on earth was Maple? I had a friend who's last name was "Oak" but I couldn't imagine that Appa had a friend called Maple. I had absolutely no clue what to expect as I clicked the "Answer" button and muttered a very questioning "Hello" into the answer-piece. A brief crackle of static later, "Hello" comes the very familiar voice of my husband. I had to laugh. It wasn't Maple then. It was a very simplified spelling for Mappillai (meaning son-in-law in Tamil) or simple Map-le (to be pronounced as Map-lay). LOL moment.
