Communication is the exchange of ideas, feelings, or attitudes between two or more people. We communicate continuously in many complex ways. We speak, scowl, write, preach, touch, smile, sit, stand, cry, and stare; all of these behaviors communicate an idea. Whether we communicate the intended message or not depends on our effective use of communication skills.
