You take the person's face in your hands and a tear falls or a laugh bubbles up, and that's when you cry. You cry for every person you've ever loved, your mom and your dad. All the people you used to love but don't anymore. You want to actually curl up into a ball so small it's visible only to that person, then you want to press into their stomach and disintegrate into their skin. Being in love is wanting to disappear.
And all the other times, when you've been alone so long you nearly forget what it's like to love someone, you can allow yourself to remember. You can lie in your bed with a book and a pen and you can write in cursive letters, Sometimes I want to fall asleep with the light on. And then you'll wake up at 4 a.m. and the lights will be on and you'll crawl blind to switch them off, and then just before you drift off again, there it is, that feeling you haven't felt in this life.
You pull the blanket up around your nose, take your face in your hands, and cry. You pray for a sign.
