Native Blood or Alien Blood?

 I wonder which one would you choose my blood type. Please comment first your guess.
My blood type is B.
 On the internet,
A has a some features : timid, keen, fragile, but keep promises well and have a strong patient.
B's feature is clear character, arbitrary, psychopath, but smart, concentrates well, humorous and creative.
O's feature is active, have a good leadership, flexible and have a warm emotion about people.
AB's feature is calm, cool, patient, act cold-heartedly, not be angry with small things and set a accurate plan.
 I think it doesn't match, but my aunt says, I belong to my blood type. Actually some match with me.
Because I usually hate my unintended plan, and I stick to only my life style. But mainly It is not true for me.
 Suppose that blood type shows character correctly, though I want to date with anyone who likes me, I'll choose O because I want a natural friendship not so special and difficult.
 I think our teacher Erika's blood type is AB. Because she is very calm when she speaks something, and she plans everything. So I think so. And I want my teachers would be B. Because I think it might be interesting to get along with special and strict character, and I also love humorous lessons.
  I wonder which type you choose belongs to me. To know my type block the first paragraph's vacancy.
