Actually, if you think about it, she isn't that mean. Ruby shows up, knocking over Weiss' cases of explodium, seems oblivious to the danger of that, and then blows her up. Some other girls then shows up and starts dissing her and her family. Not exactly the best of first impressions. Weiss does try in her own way to make it up to Ruby. The whole act of bringing the pamphlet to Ruby is suggestive of someone who was trying to be nice, but was too headstrong to admit it and covers it with feigned rudeness.

When they first encounter each other in the Emerald Forest is when you sort of see that Weiss is not that bad. Her reaction was to walk away, but it wasn't like she was angry or upset about it. The expression she had was more one of innocent bewilderment and the reaction was just quietly avoiding a difficult situation. Clearly she was more upset about the only alternative being Jaune.

From then on it is pretty obvious that Weiss is a fairly innocent person and her attitude is largely a reaction to Ruby's reckless and disrespectful behavior. Seriously, although we don't see it, she obviously went along with Ruby's absurd plan to hitch a ride on the giant Nevermore. You don't go along with that sort of plan unless you are crazy too or very soft-hearted. Weiss is very much the opposite of crazy.
