Because the word "love" is appropriate to describe both how I feel about you and how I feel about ice cream,
Because I can no longer use the word "literally" literally when I try to say I literally am dependent on the sound of your breath encouraging my lungs to sync with yours and find sleep when I'm with you, curing my twenty year fight with insomnia, literally.
That you are literally the reason I can chase my dreams because without the sleep you give me, I wouldn't be dreaming at all.
Because "you're the best" is said to even our least favorite coworkers, when I would use it to literally say "You are the best", the most superior to all that I love, and I use those words correctly when I say that, and if "love" is the word to describe my feelings for you, then I don't love anything or anyone else because what I have for you is literally the best.
