The golden rule thats been implanted in our minds have been a major factor of us growing up and many things that we learn. Such as when we speak, we filter what we say before it comes out of our mouths. Will this offend him/her? Is this relevant, do I really need to say this? Do I really mean what I say? Such questions act as filters in our mind when we think of something to say and this is what makes someones who they are and how they express themselves. These are very important when it comes to first impressions because when you first meet someone they form a understanding of who you are and how you would act from first impression, how educated you are, do you have manners, etc. are all interpreted from the first interactions. Thus creating the importance of first impressions and talking filters.
