Problem solved!

I never answered the phone and young patient stopped calling.  I was at the point of on his next call having a guy answer and act like an angry boyfriend, but thankfully it never got that far.  Although his calling at what I labeled booty call hours was wildly inappropriate.  You don't call someone at 1230am!  You just don't do that!

I just hope he doesn't get admitted as a patient back on our unit before I find another job!  That would be super awkward!
