I am so #*($&% sick of people assuming I am the primary parent. They say they don't, but they do. I'm filling out my extended care forms for school. First section, kids and parent's name and addresses. Father's info goes first, fine. Second section, phone numbers, Mother's phone # goes first, then Dad's. NO! Don't call me first. Call him. If I'm at work I can't come get my sick kid, I'm taking care of sicker adults. The former secretary at the school actually told me when I tried to tell her to call my DH first in an emergency that, "She couldn't change that, it was in the computer." So sure, leave messages on my cell phone that I can't answer because I am rushing someone off to the OR. Or interrupt my friends important executive meeting to say that her son is sick because the called her house first an no one was at home. Her stay at home husband was at the store, call his cell! I wouldn't mind if they listed it in that order because 80% of the time it's the mother's or whatever, but put someplace for me to indicate who to call.
Oh and I could go on. Mom's need to volunteer. They get guilt if they don't Dad's get praised for just showing up. I frequently go on strike now and tell them to deal with my DH with scheduling issues. Yeah, he sucks at it, but he's the one that will take them more than 50% of the time and he's the one that I will have to tell 3x if I do the scheduling. Let him do it.
