You cannot be sirius!
I love the dogstar. Well, while you picked the brightest one, I picked the um...well...mine is the most...um..I guess mine doesn't have such a distinction, but it sure looks cool in the summer.
Altair, for the "space"cially illiterate is a star of the summer triangle. It's also part of the constellation Aquila, the eagle. It means the flying one. I picked it because I've finally reached that point in life where I feel I'm no longer grounded by my demons (fears, worries, uncertainties). I've been freed and am soaring higher. The demons have become my angels as they make me complete. You have to embrace all that you are and then let go.
