It's a sad moment when u have to say goodbye to your friends upon graduation. What to do, it's part of life, we grow and we change. We can't be at the same level forever. So if this is your 3rd year, do something meaningful with your frens and for your friends, at least u'll have something sweet and memorable to store in your mind when you say byebye. No point regret later because time will never stop for you.
