The weaknesses of a Sagittarius lady include the traits that might be noticed during communication with her. It's a bit of tactlessness, impulsivity, inconstancy, and fussiness. Sometimes she is harsh and rude while speaking to people. Although this woman doesn't see it in most cases and easily takes the conversationalist's similar attitude as an offense, beginning to show aggression.
Sagittarius is very impulsive, and if she wants to do something - no one can stop her. It doesn't really matter that the steps she makes are useless. Even if everything was planned a month ago, this lady prefers doing all preparations at the last moment. Vanity is her second name.
