I think we are in culture that loves to scream out "relationship goals", so when I saw this tweet, it made me think that this should be an ultimate goal. This statement to me, represents the soulmate type of partner. When the person you are with romantically is also you're best friend. What's a better feeling than that?? Someone that knows all you dirt, loves you anyway. They know all the good qualities which becomes the icing on the cake.
