according to Zastrow and Kirst-Ashman, "We generally let only people we are emotionally very close to entering our intimate zone" (454). The intimate zone according to Zastrow and Kirst-Ashman covers the skin areas and approximately 18 inches to the outside (454). Therefore, the fact that the two individuals were in very close proximity is a clear indication they are very closely involved emotionally. Subsequently, I could tell the two individuals were in a happy mood. As they walked past where I was seated, I could hear them chat happily and I could also see occasional smiles on their faces. There is much to learn about nonverbal communication from these two individuals. For example, one can easily tell the feelings of another individual through his or her facial expression (Zastrow and Kirst-Ashman, 452). Smiling is an indication of happiness or contentment. Other than facial expressions, gestures can also help tell the feeling of an individual (Zastrow and Kirst-Ashman, 452). Two people walking as close as possible to one another is a sign of trust and hence there is emotional attachment. In a nutshell, people communicate either verbally or through body language. Facial expressions and gestures expresses the true feelings of an individual.
