Your best friend is saying all the wrong things, wearing the wrong clothes and generally behaving in a way that guarantees that her new relationship will crash and burn. Are you any good at telling the truth in a way that will help her see the light?
Virgo and Libra are especially good at putting themselves into other people’s shoes, and giving a sense of sympathy. That's a good first step since being too direct in these circumstances never works. That said, Virgo can sometimes point out too many failings, and Libra may be a touch too cool. But overall, these two signs will set friends onto a better track.
Pisces may be overly understanding since they really don’t like confrontation. But in their intuitive way, they'll find the right words to point out what’s gone wrong. Cancer will also offer a shoulder to show that they're on their friend’s side, at which time they're able to slide in a few constructive words on better behavior.
The truthtellers of the zodiac on the other hand will leap in with both feet and not generally get a great response. Sagittarius, Aries, Gemini and Aquarius tend to tell it like it is, which isn’t always what the friend-in-need wants to hear. Though sometimes a thunderbolt is what's needed, it can offend the more sensitive souls.
Leo and Scorpio want the best for their friends. Leo may find it tricky to understand what makes anyone behave in a way they never would themselves, but they can often find an inspired way of offering advice. Scorpio has a deep understanding of emotional pain and will do all they can to ensure their friends saves themselves from future grief.
Taurus and Capricorn will be completely forthcoming with practical help. They're not big on analyzing why their friends act stupidly sometimes, but they will lend a hand when it comes to advising them on how to dress, behave and act well.
