Finding out that you and your mother are using the same sort of contraceptive pill is weird.
Not as weird, however, as when she tries to borrow some off of you.
"You don't want a baby brother or sister, do you?"
"Ow, my ears! You better be talking about the second coming of the baby Jesus."
"Yes, yes I am. And I know you dislike religion, so hand them over unless you want the messiah crawling around and vomiting on your carpet."
This is some sort of child abuse, surely.
