What would life be without friends? Not worth living, according to Aquarius. You don't just have (lots of) them, you need them.
Some people say that their spouse is their best friend, but your spouse is your spouse (and you love him or her to death!)
Friends are the ones who are as nonjudgmental about you as you are about them. They don't try to "fix" or "improve" you, but they'll honestly tell you what they think - and you love them for that!
Besides, your spouse doesn't want to hear your monologue about that thingamajig you don't really need but so desperately, passionately want. That's what friends are for!
