Clinic day

I had pediatric GI clinic in the AM, then adult internal medicine clinic in the PM today.  Usually, clinic is pretty uninteresting, but today...

Me: (seeing a failure-to-thrive patient) how many times do you feed the patient?
Pt's mom: Well...you see...I used to feed him every 3 hours, but people were telling me that's not good.
Me: Okay, so how often do you feed him?
Pt's mom: So now I feed him every other 3 hours
Me: So...like every 6 hours?
Pt's mom: No...like every other 3 hours
Me: Okay, so what times did you feed him today?
Pt's mom: 5, 8, and I'm going to feed him again at 11
Me: That's every 3 hours
Pt's mom: No, that's every other 3 hours

Later on in the day...

Me: So does anyone else in your family have the type of cough that you have?
Pt: Yeah, my nephew does
Me: Oh, okay
Pt: He's my son's son
Me: Excuse me? Your nephew is your son's son?
Pt: Yes
Me: ..................Okay (writes CONSANGUINOUS FAMILY in all caps on note)
