My friend and I are fighting. I want us to continue being friends, but we're both stubborn. Oh, no, that's not it. The same qualities which help one make friends also aid in keeping them. Oversensitiveness, shyness, jealousy, gossiping, being too critical, and wanting one's way are faults to avoid.
Jealousy destroys friendship.
Jealousy sometimes breaks up friendships. Almost everyone is capable of jealousy. Sadly enough, it is not unusual for girls to be jealous of and 'catty' to other girls. Incidentally, if you are worth-while and deserving, popularity and success will not turn your head. You will find time to remember and see old friends.
