Your name of Pennebaker makes you independent, self-reliant, and determined. The average person would never realize the true depth of your nature. It is challenging for you to reveal your deeper thoughts and feelings, as you tend to be self-conscious, reserved, and secretive. You desire affection and understanding but often leave the impression that you want to be left alone. The crashing of waves against the shore, mountain peaks silhouetted against a dusky sky, are surroundings that help you to experience peace and contentment. You enjoy exploring and observing animals and birds in their natural surroundings. Being sensitive, you can be easily hurt and offended, taking seriously the comments made in jest by others. You could excel in scientific research because of your ability to concentrate and remember details, or you could be inventive along practical, mechanical lines. There could also be a sensitivity in the heart and respiratory organs. A very individual, independent person, you live within your own thoughts.
