I don't consciously mimic anyone including TV or movie characters, but I am bound to simply because everyone learns from what they sense around them, especially from other people and that is also how we learn to speak in the first place. When we are born we have very limited built in instincts and everything else is learnt from our surroundings, especially from people and at first mostly from our parents / guardians. In fact speech in general is 100% mimicking various combinations of lots of different people. This still goes on at a slower pace even into adulthood, for instance if you move to another region where the same language is spoken in a different accent, at first everyone sounds like they've got a strong accent to you, but eventually after a number of years they will sound normal without any accent and you will also speak with their accent. It goes beyond just speech however and what we sense around us, especially from other people also greatly influences who we are, yes I believe we all have our own unique personality, but how much of this was created by other people around us and also by the media? Yes we also pick up what we watch on the TV and from other media, and it's mostly done subconsciously, that is partly what makes the media so powerful and it's also extremely influential. Many very powerful people know the true power of the media and use it to their full advantage giving them a level of control over mass numbers of people, in my opinion it's often not good either. The people who are the fastest and most greatly influenced are in fact our children, but adults can still be significantly influenced too. As I've written on a number of occasions, power = corruption! Most people accept that advertisements are influential and it's a fact they they work, but how many children's programmes and even movies do you think might have underlying and purposeful influences on our children?
