Fullstop for a subject title??

Today I had a minor argument with the secretary. I was about to submit my report when she insisted that I had to amend the report, because I did not use fullstops at the end of each subject title.

Her idea of the correct format was:
Subject titles must have Fullstops.

My idea was:
Subject titles do not have Fullstops

Well, I decided to give in after some 10mins of pointless arguing (the report was due in 20mins' then.. and she refused to accept the report unless I amend it.)

So, I added fullstops to the subject titles.. and now the titles look like this:
Subject titles should not have Fullstops, but I added them anyway.

Well, I thought all was well then until she made a comment, which left me flabbergasted.. ''I think you should underline the fullstops in the subject titles".

!#*%$@^&*?>?!!

Man, some folks can be so anal!!

Anyway, I told her that she could underline the fullstops if she must, but I prefer to save trees and printer toner (she's always complaining about folks bursting her budget you see).. And that I still believe subject titles don't come with fullstops.

Oh well... Can someone enlighten me please? ;p
