Boys who go to college should be almost eighteen. When the children are walking in the street, they call you uncle. Men should be strong, everyone has troubles, but they can't cry when nothing happens. Your parents will be sad when they see you cry, and others will laugh at you when they see you cry.
Going to college is a process of growing up slowly in a new environment and life. Slowly, you will find that crying can't solve any problems. You must face life bravely in order to find the beauty of life.
Good luck and happiness!
