I've had someone scream at me because I told them to level Basic Skill instead of the key to sit.
I'm sure you can understand why; He wouldn't have been able to sit anyway, but I did actually tell him the key for it after mentioning that he wouldn't be able to use it without raising his skills. Since when he initially tried to sit down, it didn't work, he'd instantly jumped to the conclusion I deliberately told him the wrong key and proceeded whore out his dictionary of swear words.
Stuff like that's why I find it difficult to "click" with the community of any online game community, let alone specifically RO.
