Your first name of Thoai gives you a poised, gracious, and reserved nature. It is not easy for you to be expressive, especially when you feel deeply about something. As you live much of the time within your own thoughts, someone can be speaking to you face to face, but you will be thinking about something entirely different and have closed out the conversation. You are not spontaneous nor adaptable to situations where there are constant interruptions. Light pleasantries and sociability do not appeal to you as much as reading, study, or outdoor activities. Because of your strong concentrative abilities, you can shut noises and activities out so completely that you may not even hear someone calling your name. Once you settle in to accomplish a task, you like to carry it through to completion, quietly and efficiently. When called upon to extemporize, you could be self-conscious and nervous as you prefer to be fully prepared ahead of time to handle situations and experiences. Any weaknesses in health tends to affect the heart and respiratory organs or the female organs. You love to read and can develop great powers of concentration.
