sometimes i regret to make a friendship

1.
when i meet people who i don't know before. I'm  trying to see the person's positive side because i believe that it is the best way to be a friendly person and to make a friend.
sometime it brings good result but sometimes it isn't.

Recently i regret my behavior ever than before. i was rented a house and shared it with other two people. All of us made rules for the better living environment. For example place that we share should be cleaned up by ourselves, after using toilet or kitchen make it clean so that we can provide us a clean place. All of us have to have a responsible for every single items or our behavior. It is easy and only thing that i asked other  people.

I remember the problem occurred at just before christmas day. One of my roommates invited her friend secretly. I don't care and the other roommate don't care at all those things. So the next day that the unknown person stayed one night i asked my roommate that if she wanted stay here it would be good for her also if she kept a rule, i and the other roommate would not care about her what she did. Beside the unknown person didn't have a room to stay few night because she was a traveler.

After two days later when i came back to city i found that all of our house's door was often and the light didn't turn off. i felt almost mad and felt embarrassed So i called her and asked what had happened our house but she said that she didn't do anything wrong. Even though she did the worst thing to us she didn't felt any guilty at all. As a result of her behavior i had to ask her not to stay our home. Even though i was trying to be good to others they didn't  show any responsibility for our lost. Until today my roommate didn't say sorry about her friend's attitude. Being a good person is not easy and it isn't alway good because they might take advantage of me.

Henrietta did not know about what had happened her. Only thing that she want was a treatment from the cancer. Without saying to her, doctors were taking her cells to their lab and tested it. As a result they found a new method to cure disease and earned a lot of tension from public. Doctors took their advantages from its benefit but they didn't pay for her or her family. Because they thought that they had to deserve it. Many years ago it was common for doctors if the patient would be died in few months later or they had lots of problem for cure they decided not to talk to patient. If i were her, i felt anger and refused to go to John Hopkins hospital.
