Are others' words out of politeness or sincerity? How to judge this is constantly a headche to me. 

I am a person with very simple thoughts, I would always take others' words very seriously. That is to say, I would easily believe what others say, because when they are talking, they perform very sincerely and amiably. A very common situation is that, someone enthusiastically promise that I would come for him whenever I need his help. How inspiring and appreciated the words are? And I take them seriously. But when I really need some help and find that talker, he behaves a little indifferent and unfriendly, and his expression seems indicate ”why are you here? How can you think of me for help? I do not think we know each other very well”. When this happens, I feel so embarrassed and I really want to find a hole to hide in. For me, I feel so hurt, badly hurt, like my self-esteem is severely humiliated. And I would inwardly blame myself” you are so silly, you even can not judge politeness and sincerity, you such a stupid girl”.

I really think people intimate or not should sincerely treat others, if just out of politeness, then do not promise something easily. Believe it or not, I indeed do believe.

I, stupid girl, should learn to be smart, and should not take everyone’s words too heartedly, or I am always the one to be hurt.
