As a Pisces, I must say I resemble that remark. Well, maybe not. Sometimes, maybe. But mostly, no, I can stick to one thing, more or less.
My choices:
Leo - yes I MAY be wishy washy, but stop YELLING AT ME. I will NOT make up my mind. You are so totally not the boss of me. At this moment. Maybe later you can be the boss, but not right now.
Sagittarius - more of a love/hate thing, really. I hate my sister, but my late husband was a Sagittarius - he was all fire in a good way - a cleansing, clean fire. That b----- of a sister of mine is negative, icky, fire. More of a fire full of disgusting creosote - it pollutes rather than cleanse.
Taurus - Stop trying to make me do what you want...remember, at the heart of every little Pisces is a Puffer Fish. Push enough, and we will PUFF into little cute balls of sharp spines.
Oddly, I do get on okay with most Aries, though they can be a bit feisty, it doesn't bother me. I have an Aries Moon - for what that's worth.
