Dont know y ..!!

Recently i had a squabble with one of my friends. She has completley misunderstood me and i was very upset. There was no way i could make her understand how wrong she was about me. But even though i wasnt wrong, i felt very guilty for whatever has happened as if its my fault giving her such wrong impression.But i really couldnt help it. I dint understand y i was feeling so. The next day she has called me up,started abusing and i just kept quiet saying OK for everything she said. Me not responding has irritated her so bad that she started yelling at me like anything. I told her just bring on everything thats in ur heart, i am hearing. After she said she is done with it i hanged up . Later i felt so peaceful as if i m out of it, while she started feeling guilty for abusing me and feeling angry . Now when i sit back and think of whatever has happened i am very surprised to see the way i handled it . Had i started abusing her back like the way she did, things would had been worse.
