回複：it is a tricky thing to define sexual harassment.

It is interesting to know. The problem is we joked to each other too much before we worked together. We were collegue for about 6 months and that was 2 years ago. For about a year and half, we called each other once a while and had lunch together. The first couple months we worked together again, he was still acting like that and now he seems realized something and stopped himself.
