An Unsolved Question...Becomes A Hidden Poison

Everything, every question has answer itself.
If the answer u are thirst for but if the only person who know it reluctant to give u. What u have to do is attempt everything that he can acknowlege u or to make the person feel comfortable over u.
Let's say a situation whereby a person just suddently abhor over u but s/he refuse to let u know why. Tell me,what will u do because there will be an unsolve question leaving there and everytime whatever u do some other things, the focus will not be 100%. This is even worse when the person is your housemate who u have to face him/her everyday. Just don't know why? and what is his motive? Did I hurt him before? No, why should I do this for him? Is he wanna see me suffer like this in order to let himself feel happy??I believe real people is not bad. What trigger them to commit something, there is a reason behind it. And now, what I want is zero rival, and peace man.
