even at my closest point of marriage, his mom always stressed I call her by her first name...but I called her Ms. (first name).

Now I will say I called my sister's dad's mom Grandma (first name). And I called her aunts and uncles, aunt and uncle (whoever).

It just seems odd to me, and it always has. I really can't call someone who isn't my blood parent, Mom or Dad. My family is mixed, some of them do call their in laws mom and dad, some don't. It's personal preference. but when these relationships aren't long lasting, and aren't cemented in stone, why bother?

Like this kid starts calling you mom or dad, y'all break up. Y'all don't have kids. Divorce done. You get married to a new woman or man, now you have another mom or dad? That shit is too much.

Nah, my dad is my dad. My mom is my mom. The rest of you are just there.
