It drives me insane! This woman is in her 50's! When she calls me she ALWAYS says "Heh-whoa Mawissa!" Then she will speak normal, then go back to baby talk to say goodbye.
I always want to scream at her and say "My name is Melissa! Not Mawissa!"
My daughter has also picked up this habit from someone at school. I can't stress to her enough how much this is not okay!
