Woman with Blood Type AB

So, following the previous post, I'm gladly to say that I GOT THE JOB~
Although it's still in the probation period but I'm sufficiently happy right now.
I hope it will go well and I can work there for long long long long time.

Anyway, today I just want to speak up my mind about how sometimes people connect blood type with personalities.
Truthfully, I'm one of the believer.. ha ha..
Some people call me stupid because of this. I remember one of my classmates said to me that if there is a connection between personalities and blood type then whole world will be easy to control because there will be only 4 types of people.
That's not wrong as well anyway, but I believe that people with a same blood type have similar personalities although not necessarily same.

My blood type is AB.
And I actually really like and love myself.
From what I remember, people with blood type AB can easily change their minds, have different way of thinking than others, don't like to be ruled by people, and so on.
I actually find this really accurate with my personalities.
Sometimes I also confused about what I want because my mind continuously change -_-
I don't like to rule people and to be ruled by people. However, I follow an official regulation set by an organization very well (like company's rule, school's rule, etc). But, I just can't stand if merely someone want to tell me this or that.

Supporting my opinion, I found one South Korean song called AB형 여자 or Woman with Blood Type AB. Some parts of the lyrics goes like this:
수많은 매력을 갖고 있지 - Have lots of charisma
외로움 정말로 많이 타 - Easy to feel lonely
하루 수 백 번씩 바뀌는 맘 나도 감당 안돼 - Can't handle the continuously changing hearts
드라마 같은 사랑 꿈꾸기엔 이제 어른인데 - Dreaming of a fairytale like love life
똑똑하고 유니크하지 - Smart and unique
못하는 게 없어 요리도 잘해 - Can't do nothing. Can do anything
Cool한 척해도 은근히 소심해 - Act cool but timid inside
*note: not a direct translation

I kinda feel the same with the song.
And kinda feel that only AB can understand AB?
Of course it's only my opinion.
For them who say different, who cares?
