last year i texted my stephmothe "happy stephmother day" for some reason she got offended

But what should i say to her ? I think its a bit weird if i wish her happy mothersday because of my mom but then again it feels weird not to say anything

Say Happy Mothers Day.
Mothers Day is actually not only for your own mom but for everyone who is a mother.
I wish my mom, aunts, grandmother etc every year!

Happy Mother's Day.

Basically

Girl's not getting anything beyond "Barbara" from me.

I hate mine so she's getting DUST.

Good for you. Barbara is a fat name anyways.
