So at breakfast I overheard an argument between two third year girls. Which as arguments between two third year girls tend to be didn't really rack up many points on the intellectual log. Gist of it was that Girl A forbade Girl B from looking at her W-Crew poster because Girl B wouldn't share her chocolate cauldrons with Girl A.
Whatever.
If you ignore this fight being over something completely stupid, it doesn't even make sense. Like if I have a picture on my wall and I look at it and then you come along and look at it, it's still possible for me to continue looking at it as much as I was before.
Unless you stood in front of me.
BUT assuming that you didn't do that, I wouldn't lose anything by you looking at the picture. HOWEVER if I have a bar of chocolate and split half of it with you, then that's half of the chocolate bar that I don't get to eat anymore. So in that case I HAVE lost something.
Therefore you can't compare the two quantities as if they're the same thing.
I think I'm going to go and fucking draw something now. My pencils are sharp. Unlike those two bints at breakfast.
