That 's a control. Well ,  it seems like there are two possibilities there , I mean  i it seems like  if you have just  two people it 's not  really , y like a meeting , w is not as similar as the rest of the   of the sample. It depends on what you 're after , of course , but  It seems like that would be more a case of the control condition , compared to , uh  an experimental  condition , with more than two.
Mm - hmm.
Well , Liz was raising the question of  of whether i it 's the number  there 's a relationship between the number of people and the number of overlaps or type of overlaps there ,
Mm - hmm.
