There's no more dignified sign than yours, Leo!
With the Lion as your symbol, your sign of Leo has the royal bearing. You're proud of your strong and noble physique, and carry yourself with a great deal of dignity.
If we had kings and queens these days, you'd probably be one! This quality comes in especially handy with friends. Some may not have the native confidence you pull off.
But they could take a page from your book and carry themselves the way you do, with shoulders back and big smile. Fake it until you make it may just give them the royal bearing that comes so naturally to you.
