Harmless fun and bullying(欺负) separated by a very thin line.This line is crossed on a daily basis,without being known.This full extent of this line crossing isn’t often felt until much later.Blind eyes are often being turned,and the problem is becoming more and more serious.
Harmless fun occurs when nobody has hurt feelings and laughter follows.There is no harm in the fun,and all people can enjoy the joking.Bullying occurs when someone is looked down upon.Not every joke is funny,and sometimes we can cruelly hurt somebody without our knowledge.
The most difficult part of the line between harmless fun and bullying is the simple fact that everybody has their own line,and even it’s different from time to time,depending on a certain character.Everybody has their own limit of tolerance,and harmless fun that is close to bullying usually gather up the bottled emotions that are ready to break out.No matter how strong the friendships are,words can treat them apart from the root,destroying the very foundation that they have been built upon.
The key is that the line should never be crossed.Harmless fun has its time and place,since laughter is the best medicine for what worries you,but it should never be taken to the extreme,where someone is feeling down.
 The best possible way to ensure that you aren’t the one responsible for linecrossing is to think before you speak.We should first try to understand before we try to be understood.If the words you feel like saying to someone aren’t the words you would want to say to your parent,brother,child,or good friend,then chances are that you should think of something else to say.
Saying things behind someone else’s back is no good,either,because those words often find their target finally,and usually the comments have been misunderstood and the intention,while perhaps harmless,tends to turn towards bullying.
