Does not shake hands

Bollinger does not shake Sulkowicz’s hand at the graduation ceremony. As Sulkowicz and her friends ascended the stage, Bollinger, who had been shaking the students’ hands, turned his back and picks up a water bottle. Ms. Sulkowicz leans over the mattress and tries to catch his eye, then straightens up and keeps walking, shrugging with her free hand. Sulkowicz:

I even tried to smile at him or look him in the eye, and he completely turned away. So that was surprising, because I thought he was supposed to shake all of our hands.

A spokesperson for Columbia denies the move was on purpose:

The mattress had been between Ms. Sulkowicz and Mr. Bollinger and that no snub was intended.
