Is it mean of me for not calling my mom mom

A mom appreciates being called "Mom." I feel it is mutual respect... it is not like someone's kids being called son, daughter and son. They are called by their name. All kids mostly call their mom, mommy or mother even though they know her name. They are also, on occasion, in group with other kids that it is easier and more exceptable to call her by name while the rest call her Mom. I would never be so rude to my kids as to say, I don't know this you are referring to by name . My name is not "Mom," my name is so and so and I am a mom. All will be thankful that their children honor her by calling her Mom but she would never force that on them. It is something that is earned. "Any woman can be a Mother but it takes a special woman to be a Mom." In other words, you have to earn it.
