happy mother's day

seriously, why would one choose to wish a stranger "happy mother's day" when said stranger is sans child?

after my much needed pedicure this afternoon, the girl who processed my payment said, "bye. have a great mother's day."

when will my ovaries be big enough to break down at a time like that and announce to anyone that will listen that i'm barren? i'm not, but seriously, how many free treatments would that display have gotten me?
