It's not the working that's so hard. And it's not the child. It's the two together, specifically the part where "time to myself" comes out of "time to sleep". At least the spousal unit gets a couple hours while the Pumpkin nurses to sleep.
My one-year review is this month. If they tell me to work more, I think I'll bite someone. I'm still not sure if my boss keeps assigning me difficult projects as a not-so-subtle hint to work more, but HAH! I ignored much more passive-aggressive people for almost seven years. I scoff at this.
That is all.
