Too much coffee for some?

This was an interesting outcome of timed exposures of groups.  I was looking for the common swirl of subjects passing through and around the pictures.  Some pictures where more interesting than others then I saw this one.  I’m thinking that because the woman is touching the table, something stationary, that it encouraged her to remain stationary herself. This is a 5 second exposure and for the most part she didn’t move.  I find it interesting how much the rest of this group moved in that 5 seconds.
