"Well. It wasn't any of my business before the other day. But 'since you were sixteen' incorporates a period of time between us getting together and having that perfunctory monogamy conversation. And I'm under the impression that even when people are not being monogamous they're at least entitled to information on the subject of how they're being not-monogamous. So there is some disapproval. Yeah. The 'when' should've been 'before saying you wanted me to hack my brain so I could date you'. Sometime before then."
