Junkie logic

An elderly relative for whom I am somewhat responsible has a serious prescription drug addiction.  The other day, said relative took a few too many pills, and I was present when the nurse in the residential care facility spoke to the relative.  This dialog ensued:

Nurse:  You took too many pills.  That was dangerous.

Relative (still slurring heavily several hours after the fact):  No, I didn’t.  I can tell I didn’t, because my speech wasn’t slurring and I made total sense.

Nurse:  You were alone in your room, so how do you know this?

Relative:  Because I talked to myself.

Caring for an addicted person is challenging, but it sometimes has its humorous side.
