Fighting the urge to throat punch my husband

My husband (who works construction) was saying how tired he was. I agreed, as I'm 8 months pregnant even though I do office work. He said "at least you get to sit down all day". My response was, "I'm growing a baby, everything makes me exhausted". And he said, "growing a baby only consists of eating more"!! I could have smacked him. I know he didn't mean anything by it. He has no idea how exhausting it is. But my hormones were definitely hard to control at that moment! Lol.
