dear diary
today i wanna tell you something that i felt very inhuman. i was going through a street today and then i suddenly saw a man on the road who had met with an accident. he was bleeding very badly. no one was ready to take him to the hospital. everyone just stood there and watched him. i had pity on him. i lifted him in my hands and took him to the hospital. the doctor treated him and after sometime he was all right. the doctor told me that had that man not been brought to the hospital at right time he would have died.
talk to you later .. bye for now
yours loving friend
