And then you live with THEM for 10 years, and then they all get divorced and remarried and you then get more moms than grandmothers!
in that case, mothers day would be a riot..
Wouldn't the one who gave birth to you be your real mom?
Well say your mom got married 4 years after you were born. If your mom got divorced from that person 20 years later, would you still not considering them your parent just because they aren't your biological parent? It works the same with lez parents, even if they're not biological they took care of them and raised them. You don't have to be blood to be family.
