RE: falling in love
The two of you start talking about your feelings and your feelings float outside of you like vapours, and the mix together like a fog. Before you realize it, the two of you have become the same mist and you realize you can never return to being just a lone cloud again, because the isolation would be intolerable.
...And when you meet someone and fall in love, and they fall in love with you, you ask them, "Will you take my heart - stains and all?" and they say, "I will." and they ask you the same question, and you say, "I will." too.
