Why does Brutus seem so vindictive? "Oh, you want money for staying home all day, cooking, cleaning, and being the main caregiver for our child, huh? Well, I want compensation for when I mow the lawn and...change light bulbs...and...uh, all the other things I do around here!"
I always figured the salary for a housewife/stay-at-home mom should be spending money on herself and the family with impunity but Brutus complains about that so a tip jar is the next logical step.
