When my friend met me after a long.
My friend was once in a serious trouble. He desperately needed money. I helped him, but after that he was not in touch with me. Today, after two years, he met me. He apologized to me for not returning my money. I forgave him. When he left, I noticed that my wallet was missing. Luckily, it was empty!
I had a gut feeling that he would create a problem for me. His betrayal had made me smart!
Do you have any such friend?

OMG It would not be right to call a person a friend who has already helped you and disappeared, and when he meets you again, he has only harmed you. Such people are called mean. Thanks God I have no friends like him.
