If your birthday is on the 21st day of the month
You are curious and a true follower. You can please someone so much that it seem like you are trying to charm that person. You hide your disagreement under your smiling face. This is a charming quality of yours.
You are quite unlucky in love. You are loved by someone you don't like while your dream man is so far away. Your love life is occasionally under turbulence. Sometimes you don't have the clear view of the guy in your heart.
WOW. This couldn't be more wrong. Polar-opposites-wrong.
If your birthday is on the 4th day of the month - you usually think before acting which makes your life quite easy. But you often are the one who give yourself a hard time by being paranoid. People might not truly understand you but you are really nice to be around. You are cheerful and friendly.
Your Love - still water runs deep, that's what you are. You always surprise others with your new character when you are in love. Your love trap often comes unexpectedly and your love life is full of surprises.
i believe that the time you start to form an understanding of your surroundings can effects your personality in some level. so for example if you start to form an understanding the first time when its cold winter time and snow all over it could make you bit different person that if you would understand the world as warm place full of life for the first time.
