Pet peeve here.
People who refer to me as “Mom” when I am not their mother (this thankfully ended with my kids childhoods. Pediatricians and other medical professionals, teachers, I’m looking at you. ) Just overheard this today at a pharmacy.
People who refer to their own mother as “Mom” when not talking to their sibling or other parent. (As in “Mom is coming into town so I’m stopping work early.”) This drives me bonkers. A co-worker did it today. I’ve told my kids to NEVER do this. Ever. My name is not mom. Say “MY Mom”.
