Phone-related neuroses:

So what do you do when you're in physics lecture and you get three missed calls from a number you don't recognise in the span of four minutes? Do you:

a) Call the person back once lecture ends
b) Get up from lecture and call the person from the bathroom
c) After class, look the number up in a reverse telephone directory to at least identify the city the caller is from from area code
d) Ignore the call
e) After doing b), decide it's probably someone calling from their office and wait until after normal business hours to call and hear the person's voicemail

Just trying to determine how neurotic I am.
