I love Katie & Joshua from Season 4 of So You Think You Can Dance.  Obviously part of the reason I like them is because I love dance and they make great dances!  But what I really love is their relationship...

Check out a few of their dances here...

They are both amazing dancers individually and with other partners, but when they dance together, they are absolutely phenomenal!  They are so in tune with each other, aware of what the other one is doing and how they are working together, moving together.  There's complete trust - and communication.  They bring out the best in each other and really, truly make each other better dancers.

That's what a wonderful relationship is to me.  Two people who are amazing individually, but who are even more phenomenal together - who really bring out the best in each other and help each other create more, live more, and love more.
