I was at a large outdoor departmental party attended by grad students, postdocs and faculty. I’m sitting at a picnic table with three other men and one woman, a new postdoc who arrived just weeks before. A full professor walks toward us with a chair in hand, apparently intending to sit at the head of the table. When he arrives and notices the attractive new postdoc, he sets the chair down, leaves it empty, sits right next to her and starts chatting with a warm smile. It wasn’t overtly flirtatious, but the signal was clear: I’m open to wherever this goes. In other contexts I wouldn’t find this disturbing, but at a first departmental party it felt predatory.
