What is it about mothers? Why can they rattle you in ways that no other living being can? And this while they are obviously trying their best to be good to you. To actually help you.
I would never dream of becoming as upset or irritated if any other person would say the exact same things to me that my mother does.
My daughter just yawned. She yawns sideways. One day she will ask how I always manage to upset her like no-one else will.
