My closest friends study in the same university course as me as we all intended to study that particular course even before we knew each other. However as we are in the same field, finding time to meet up is relatively hard as the time we spend at work is extremely long. We take the trouble to meet up once every few months or during important occasions such as birthdays. My closest friends are very loyal and would not hesitate to give advice or feedback, even if it is a negative one. With ordinary friends, I tend to lose touch with them as I do not have much time to spend with the people i really care about.
