Be kind, helpful and straightforward. Going to a new school is intimidating. And costs a fortune. There are all kinds of pressures to excel. I’ll bet that somewhere this guy is agonizing over what he said to you and is worrying if he offended you. Or else, he is clueless. Nevertheless if he needs help you can be mentschlech and give him the info he needs. If you are going to be in a health related field you will probably have frum male clients at one time or another. Pretend this guy is one of them and act like a professional would behave towards a patient. It will be good practice! IF he continously makes odd remarks that cause you to feel uncomfortable, then you need to ask to have him transferred to another advisor. Bhatzlocha in your studies!
I am so relieved to know that there are girls out there like you! It gives me hope for my sons!
