I wouldn't say that Emotes scary me, but sometimes make me feel depressed or just saddened.
However, I do use "o3o", ":3", ";3;", etc. a lot, only since I think they add on to my, apparently, adorable (Called multiple times, by multiple friends) personality. When annoyed I use "-_-", since I believe it just makes me look aggravated, or just really annoyed; I mainly use it when talking about my brother.
Another few Emotes would have to be ">I" or ":I".
Sorry if I seem off-topic, I'm just sayin'.
