I'm an intern in a mental health clinic I've been here almost 2 years. Most of my fellow interns are young grad students and I'm almost 30. A few interns are also here for a 2nd year. One ofthem is a charismatic Hispanic guy who is friendly and always greets me and asks me how I'm doing. He knows I'm married, Jewish and that I just had a baby. I dress business casual so its always tznius and appropriate. Any way the other day I was in my supervisors office waiting to ask a question and this guy came by on my left side and kind of reached over to my right shoulder and kind of tickle-pinched it. Is this normal or was that trying to be flirtatious?
