Standing in front of a mirror, looking at your profile will be the way to find out which of your lips is more protruding. Of course, you can ask a family member of a friend for help. But this works only for natural lips, if you have in your upper lip, which will make it bigger, it will not be realistic. So, if it is more or less that your upper lip sticks out, then it shows that you are straightforward and honest. You hate being lied to, that is why you do not do this to people you care about, but you also do not expect that somebody may tell you a lie. That is why you are also a bit naive, you believe in everything you are told.
A lot of people may think that you are stupid because of this, but they will be blind to what your brain is of. A lot of people like you because of your good heart. You are always there for your friends and the people in need. You enjoy life, and you may live like every day may be your last.
