This one is different. But in such a good way. I love how you used chemistry, because love is supposed to be about having chemistry with the person you connect with. That coincides with the writings you create because words can have so many different meanings, and here you remember all the good times you have had with a person. One time you promised this person the world, and you would do anything for them, but time always wins and makes us grow older. Love the title, because you are the conductor of your own life and your experiences and experiments at times. Love this 5/5

You take a metaphor such as Chemistry and craft it into a somber love piece... you are my favorite because of the beauty you write... just lovely!
