No one wants to be around a person with no good manner and right conduct. I used to have a housemate who really doesn't behave properly. Being a good neighbor, it is our natural attitude to be kind to the new-comer. He asked for my cellphone number for emergency purpose (that's what I thought), I didn't hesitate at all. He got wife and whenever he was out-of-town, he would call me in the middle of the night to ask me if his wife was home already and at what specific time. Oh my gosh! Am I your wife's keeper?
At one time, too, he asked me if I need my food that was intended for my lunch, he told me that he was very hungry and that he was sick of eating from the nearby fastfood. I told him, "Ok, you can eat it. I'm not yet hungry anyway." So he did. A couple of hours after, I went to check my kitchen, (we have separate kitchen) I was not surprised that he ate them all, but what greatly surprised me was that he did not clean up what he used up. Everything was a mess in my kitchen and dining table.
Everybody in the boarding house had something against him. Nobody really likes him. But I told my one housemate, we can not go on hating him or be mad at him, because he doesn't know what he was doing. We lost in this game. It was just his manner and he did not intentionally wanted us to be mad at him, it just so happened that it didn't occur to him that what he was doing was wrong. So, instead of being mad at him, we can either talk to him about it or pray to God that he will realized his bad manner. Let's just shut up and pray for him.
