I agree with the people who said they are not going to stick their dislikes for people on a specific sign. It really does depend on the person. I typically don't like people who can't take the personal with a sense of humor, who are selfish and moody. The people in a group who act like they are bothered by other people but who are so finicky that they are passive agressive about getting everyone to go along with them or what is best for them.
My pet peeve is people who ask for small favors that turn into huge favors then when you tell them you have overextended your hand get upset like you promised them the world. F that.
If those things were aligned to a sign I would have to say cancer men and pisces women and some men. I just hate the passive agressiveness and the constant focus and exagerated self improtance.
