I expect more than half the pizza
Can you eat that much pizza in one sitting?
If you get half, you get half. If not, get the fuck out.
If you are upset about people not eating their fair share of pizza then this makes sense. However, if you just want to eat half the pizza because you feel you are entitled to do so then this is not a good reason. The pizza should be shared evenly if everyone chipped in.
I'm just saying that I should get more than half. You don't have to be so uptight about it.
Half is way too much. I'm sure you can't even finish a 4th of the pizza. Be kind and share your blessings.
