Small talk, Small meeting

We met at the online exam centre where I went to give the online exam. Though it was a small meeting. It was a good day. He was one of the invigilators there. My seat was at a corner . We were all masked up and he came to me for some paperwork and I was doing it as normal as in exams we do. Then he went back and there was time for the exam to start. I was staring at the computer screen thinking about when will the exam start. Again he came for a round then came near me and said that the password is your birth date . I said okay and he asked me that "will you be able to do it" then I was like I can do it then again he was 'are you comfortable, are you fine'.  I am like "I am okay, I will do it".

He went back and I thought he is the invigilator so he asked so much. I didn't mind at all. After some time again he came I had not written the password cause I decided that when five minutes will be left I will write. Again for a round he came, he came near me, holding the mouse asking me what is your date birth I will write it. My thought"What is his problem? I told him 'I can write it,' I will write after some time. He was stiffed for a moment and then he went back. After some time, my exam also starts and who cares now what happens. When the exam was about to be over, another paperwork was to be done, again he came at that time, I was looking at the paper only what to do at that time he told me he knew where I came from. He told me that there are many who came from there for the exam. If you feel any problems, you can tell me. You can feel comfortable, there is nothing to worry about. After that he left, though he was wearing the mask I can only see his glasses. I just know that he was also from my place but I don't know him. I felt comfortable and he helped a lot.
