“I actually like how doctors talk. I like the sound of science. I like how words you don't understand explain things you can't understand.”

“I can't understand these chaps who go round American universities explaining how they write poems: It's like going round explaining how you sleep with your wife.”

“I don't understand how meat like you survived to adulthood.”

“How do you know it's true if you don't believe in it?""I...huh?""How can you understand something you don't believe in?""Shin, that doesn't make any sense. That's like saying you can't understand leprechauns unless you believe in them.""Do you understand leprechauns?""I don't believe in them.""There you go.”

“I don't understand my feelings. I really don't. I don't understand how I could hate you so much after so much time. How, no matter how much I'd like to not hate you, I hate you even more. It grows.”

“I find it fascinating how we can see something with our eyes, hear with our ears and speak from our mouths. Although science tells us how they work, I just really can't grasp it. I don't know how everyday items like phones work. I can't even explain why a bicycle is fast. When I think like this, I wonder how many things I really understand. Yet I can live on. Because all these mysteries have joined together to keep me alive. Sometimes I admire that before I go to bed.”
