My Mother: Poor Katie has the old whatchamacallit... the old chlamydia.
My Very Pregnant Sister: Wait, Katie who is married and nine months pregnant has chlamydia?
My Mother: Yes
My Very Pregnant Sister: Are you sure?
My Mother: Yes, I spoke to her mother earlier. She's got really high blood pressure.
My Very Pregnant Sister: Um, Ma... that's preeclampsia, NOT chlamydia. Big difference! Oh my God, you better watch who you say that to!
My Mother: Oh! OH!!! Oh dear.
