Water signs can be strange creatures in my opinion. They are very sensitive to their environments and each Sun sign will do something rather different.
A Cancer will set up their home near water, or where they have access to an abundant supply. So the Cancer above me with living near a pool.... lol, yeah, that's fairly typical.
A Scorpio will CREATE their environment, rather than live in one that already exists. I once lived with a Scorpio who had a small pond in the backyard... she bought the house afterall.
A Pisces tends to be the most sensitive. And typically, a Pisces lands themselves wherever life takes them. That means, at one point, they may find themselves inland away from any real source of water...however, they seem to find watery areas. They have an internal beacon for that.
So...even though I'm an Air sign, I have an emotional Scorpio Moon...and I love the water! In fact, water helps stabilize me, and whenever I see some, I can't resist touching the water.
