The perfect relationship...

The other day I was told that Scott and I have the perfect relationship and this made me smile and confused me in equal measures. 
What actually constitutes a 'perfect' relationship and does a thing even really exist?
Scott and I have had our fair share of ups and downs. We have so far been unsuccessful in taking a flight together without bickering and we can't play Monopoly without a number of disagreements. (I blame our competitive natures) Is that normal? To me, I would say so; however others may disagree. 
When it comes to relationships, I think it's hard to pin point what is, 'normal' as I am sure we all have pretty diverse opinions on the matter and that's great. It would be mighty boring if we were all the same; wouldn't it?
I guess it's hard to judge a couple's relationship as, for the most part, a relationship is a private thing. Broadcasting your problems isn't exactly the done thing; although I could pick a few out on Facebook that are guilty of this. But on the whole, people tend to deal with their issues behind closed doors so you only ever really know what a couple want you to know about their relationship and that's absolutely fine by me. It's none of my business anyway.
As for having the perfect relationship, I translate that as we don't hang our dirty laundry out for all to see, but it doesn't mean that we don't have any. 
I once read that, we come to love, not by finding a perfect person, but by learning to see an imperfect person perfectly. A quick Google search attributes these fine words to a Mr Sam Keen. Anyway, this completely resonates with me. Scott has the ability to annoy me more than any other single thing on this planet; however I wouldn't swap him for all the Jimmy Choos in the world. 
As for me, I'm a stubborn, outspoken asshole for a great majority of the time and it takes a special kind of somebody to deal with that on a regular basis. So I guess, maybe we don't have the perfect relationship; but that we're just perfect for each other. We know all of each other's bad points and, strangely enough, that hasn't put either of us off...yet!
What do you think the perfect relationship looks like, is there even such a thing?
