I guess my  my first comment was , um  only that  um we should n not attribute overlaps only to meetings , but maybe that 's obvious , maybe everybody knew that ,
Yeah.
but that  in normal conversation with two people there 's an awful lot of the same kinds of overlap , and that it would be interesting to look at  whether there are these kinds of constraints that Jane mentioned , that  what maybe the additional people add to this competition that happens right after a turn ,
Mm - hmm.
