Buffy's "pretty tame" is not in reference to Sam, for the record. She's referring to the city and it's tendency to shake things up. And she doesn't want to talk about her sex life with the brother of the boy she may happen to want to sex up. Especially when they've just met.

So she'll glare. A lot. And then cross her arms in front of her chest. "Do you want the short version, or the long?"

Little known fact: There is no short version of Buffy's story. So really, that question should have been the long version or the really, really long version, but that's just a matter of semantics.
