I found this Picture at Tumblr, it reminds me of I song that I've been listening to lately it's entitled "Perfect Two" by Auburn. The song talks about a girl putting her place and the person that she likes on paired things that can never be apart. For example:

You can be the peanut butter to my jelly
You can be the butterflies I feel in my belly
You can be the captain and I could be your first mate
You can be the the chills that I feel on our first date

You can be the hero and I could be your side kick
You can be the tear that I cry if we ever split
You can be the rain from the cloud when it's storming
Or you can be the sun when it shines in the morning

The song also talks about how the girl would be if the boy she likes won't stay beside her, she also states that in time the boy would realize that the only thing that he would need is their presence together because they are perfect for each other.
"your the one for me, I'm the one for you, you take the both of us, and were the perfect two"

I liked listening to this song, maybe because I kinda relate to it? :))
