communication--a scientific or interpretive?

There are thousands of definition for communication. I may not know all of those definitions now but i can just simply define communication as this:
COMMUNICATION can exist in different ways, it could be through gestures, words, symbols, and signs. Most importantly, communication cannot be changed nor reversed. Or simply irreversible. Once the message has been expressed, communication does'nt have the power to take it back. Let's take saying offensive words to someone as an example. When you say you're so ugly to someone, of course, you will surely be hurting that person's feelings (unless if she's numb or what...). Well, you cannot take back what you said. Yes, you could always say that it's just a joke but as most people say, the damage has been done. He may forget that instance but it would take time for him to forget that. But, is communication really scientific or interpretive?
Well, honestly, im finding a hard time figuring out if communication really is scientific or on the other hand interpretive(humanistic). After few days of asking that question to myself, i've come up with an answer and that is, communication may be scientific or interpretive(humanistic). It just depends on how you look at communication in different views because if you would look at it scientifically, it absolutely undergoes certain process of sending messages--the SOURCE-->MESSAGE-->CHANNEL-->RECEIVER-->FEEDBACK(effect) and if you would look at it, it is obviously systemic. If you scrutinize it, it is evidently scientific because of the processes that it goes through. On the other hand, it is also interpretive(humanistic). Whatever we do, even raising just an eyebrow, not smiling to your friend when you meet along the hallway and even just looking at someone is communication. Whatever people act is easily interpreted especially if someone has the capacity or knowledge to decipher.
Well, on my opinion, communication is both interpretive(humanistic) and scientific. It comprises both characteristics--SCIENTIFIC and INTERPRETIVE.(peace! =p)
