Good afternoon, tulip! If your stomach is/was growling, you will likely concentrate better if you ate something else.
Doing dissertation research?
Yeah, I'm working in the library right now. And I can't have food here. But I'd have to go home to get something anyway.
I'm normally not very hungry throughout the day, even if I skip breakfast (which I did not do this morning). So I don't know why I'm hungry right now.
