Someone I know speaks in a reverse tree of sorts which actually does resemble a "weave", they start with various statements about the topic at hand without ever mentioning the topic, and eventually arrive at stating the topic near the end (hopefully). Sometimes I have no idea what they are talking about because they forgot to mention it until the very end when they have merged all their branches.
My mother-in-law is also a master of 'the weave'. When my wife and I visit she uses it to inform us about every possible happening of gossip and 'important events' . She just needs a key word and then she uses the chance to get all the information out in one stream of thought. (One problem is that she speaks in dialect and also assumes some deep knowledge about my wife's family relations). I often have thought of trying to map the branching. I often assumed that my wife could follow but I found out that everyone seems happy, without any deeper exchange of information.
