Your first name of Cailles gives you an independent, serious, reticent, and studious nature. You are a thoughtful, analytical person, and you know your own mind, even though you may not speak it. In fact, others find it challenging to understand you as you do not reveal your innermost thoughts unless you are completely comfortable in your friendships. You are very conscientious and competent in all that you do. You have sensitivity and appreciation for the finer and deeper things of life, the beauties of nature, music, art, and literature. You are rather easily hurt or offended. You do not express yourself spontaneously when conversing with others; hence other people may often regard you as being aloof, and even unfriendly. This name has caused you to live much within yourself. Worry and mental depression could be problems in your life. Physically, any weaknesses in your health would centre in the heart, lungs, or bronchial organs.
