In college the other day, a girl(nonJew)asked me a question and I gave her the answer. She began to put her arms around me in an attempt to hug me. What is the proper thing for me to do in that situation?(not sure if it matters but there I have no physical attraction to her)
Perhaps the best thing to do is to try move away from her with a pretext as not to offend her. i.e. tell her that you have a sudden cramp in your leg.
