With all the talk about FMILs, reminded me of when I was trying to figure out what to call my FMIL. I remember avoiding calling her anything for a while...which got awkward. Then, I noticed if she left me a message on my phone she hesitated when she said...this is...and then she would say her first name. I have decided to just call her by her first name since that's how she leaves me messages. But it's awkward for me, since we grew up not calling anyone significantly older than us by their first name, we were so quick to put an aunty or uncle in front of someone's name (caribbean culture). Interestingly enough, I asked my mom what FI should call her and she said Mrs. Blah blah blah. When I told FI, he said he's going to call her mom..LOL. I haven't heard it yet but I can't wait to see the look on her face.
So how did you decide what to call your FMIL?
