Perfect is nothing but a word to describe what appeals to you most. We say it's perfect when things go our way. We say it's perfect when two people come together happily. So you see, it's just a word associated with being content. Simply put: If you're in a relationship that puts you in a good state of mind, then, you are in a 'perfect' relationship. And if you're still looking for that 'perfect' person, keep in mind they don't need to be perfect in all that they do, just as long as they're a perfect fit for you.
