I can't vouch for the accuracy of this description of Canadian conversational styles (link via Julie), but it rings a bell -- whether because I'm Canadian, female or both, I don't know. Surprisingly, the "weaving" style can sometimes be seen as more aggressive, because it involves pushing conversational pieces into pauses. My American SO sometimes thinks I'm interrupting him. Well, I am interrupting if you assume there are rules about waiting until somebody is done speechifying even in one-on-one conversation, but the interjections are meant to build the conversation, not to be rude to him.
