What does 'Culture' mean to me?

Throughout the lessons and various videos i have seen, culture to me is what defines you, what makes you the person you are today. High culture is associated with the canon, however to me that is just a symbolizing statistic, to me that means a high culture is what a person values the most or what a person sees is superior to them. For example, culture to me is my friends and family, they are my high culture because they define me, they make me the person i am today. Also the phrase: 'To be culturally worthwhile, it has to be difficult' I believe this is the best definition of culture because it completely sums up what life is, putting in simple terms that you can't have anything good without a little bit of bad, this represents culture because its telling that if something is truly valued or rated a person will work hard at it. Furthermore a popular culture is something that is in the mainstream, which everyone has to keep up to date with and follow the crowd so they can fit in. But i think that popular culture to a person is what you keep up with or what is your interests, if something moves you or makes you escape from the world or a situation, that to me is a culture. 

Communication and Culture lessons so far...

Throughout the lessons I have attended in my first week in college, the main lesson of communication and culture which has stuck in my head is when Nina taught us 'The process approach'. This process is all about the way things are communicated and got us thinking clearly about the message of what had been said or showed to us. The process approach is: SENDER-MESSAGE-RECEIVER, this may sound simple enough ,honestly I thought so too, but when you stop and clearly analyse the message, you realize the depth of the meaning. The message square contains the content (what is being said) and the form (how it is said, verbal, non-verbal, text, email, pictorial, radio or t.v)
What is communication? the question sounds easy enough to answer but the explanation is alot more complex than first anticipated. The first week of lessons have been based around how things are communicated and the way you communicate with different types of people such as friends and family,
 Does the way you communicate change based on the type of person?
Overall communication and culture is alot different to what I anticipated it would be, I have found the first week interesting and I'm sure the rest of the year my knowledge will expand even more.
