Why friends are crazy and self minded

Sometimes my heart says what would happen if there is no friend in the life, if we just take a thought, it likes a terrible dream, thanks god I have friends. Life is so lonely if we don’t have friends but still there is a big tragedy we give pain to our friends, we hurts the feeling of our friends, we make them cry, flirt there feelings just for our joy, we lie them hide many thinks from them. We forget all the enjoyment of days and parties, we forget every thing or just ignore past events. People even do not say hello to there friends if they find them on the road. People are so much selfish and self minded. They only see profit of there own do not understand friend feelings. They act like predator how they get a chance to hurt you with sweet knife.  True friends are rarely found in this human society.
