Peter Parker: I mean, what I do sometimes requires violence, but I'm not a violent man, I'm really not. But I just — Mary Jane: You wanted to deck her.

Peter: Twice. And I hate feeling that way. Why is it that people feel the need to take whatever little authority they have and shove it down your throat? And the smaller the authority, the bigger the shove.

Aunt May: It offends you, doesn't it?
Peter: Yeah, it does.
Aunt May: Why?
Peter: I — What do you mean, why?
Aunt May: Why does it offend you?
Peter: Shouldn't it?

Aunt May: If a lion broke out of its cage at the zoo, and bit you, it would hurt, sure, and you'd be upset, of course. But would you be offended?

Peter: No, of course not.
Aunt May: Why?
Peter: Because that's the nature of a lion.

Aunt May: Some people by nature are kind and charitable. You could say that some people, including at least one person at this table, are by their nature heroes. Ben always reminded me that we each contain all the nobler and meaner aspects of humanity, but some get a bigger dose than others of one thing or another.
Some are petty, and mean, and uncharitable. That's their nature. You can hope for better, even try to lead them to be and you may even succeed. But when they behave badly, it's right to be upset by it, or hurt by it, but you can be no more offended by it than you can when a lion bites you.
