Making a good friend will help you a lot in life. When you have a good friend by your side, when you're going through difficult times, your friend will be there to always cheer you up.
A true friend will never see you depressed and walk away, he/she will always find solution. I still remember my very close friend, he knows when I'm sad, happy or angry and he always finds a way to cheer me up.
