Some time ago, I was all googly eye for a boy who had similar tastes as I did - indie music to be exact... It ruined my love for the music - ruined the only thing I loved more than anything else. It would be selfish of me to generalize that indie kids are too underground for something as mainstream as love but let's just put it as it is to make things simpler.
Finding someone who likes the exact same things as you do so much too risky. I don't want to end up finding something else to love because certain things remind me of a heartache. What is the likely chance that your identical is the person for you (and vice versa) anyway.
Of course, I have finally managed to let go of it and able to listen to The XX and Florence and the Machines once again but I think having to let go of the things I love (for a while at least) made it a lot more difficult than it should have been.
That's why I'm glad Terence and I are so different. I learn so many things which sometimes I've no interest in at all but I'm glad it's some bit of general knowledge. The relationship will never become prosaic neither.
