You don't know they exist. You are unaware that they are on this Earth. You wake up, you brush your teeth, you do whatever it takes to make it through the day, you lay in bed and play out fantasies of finally finding the right comeback when somebody is mean to you and the like, and then you sleep, and everything starts over again.
You're going to open your eyes one day and your phone will have been silent since you plugged it in at night. You are going to roll over and realize that everywhere you are not laying feels like the cool side of the pillow. You're going to shower alone for the first time in months. You forgot how much work it is to wash your hair. When you go on drives, you realize how bad you are at directions and finding where you are supposed to go. It's the little things. Their laugh, that you thought was so funny and unique when you heard is, is suddenly the loudest noise at any crowded event you go to. It's never going to be them, so stop straining your neck. You're going to stop comparing their heart to the flowers you pass on your way to work in your head and you won't even realize it. You are going stop waiting up until you are too tired to keep your eyes open. Love is a learning process. You're going to be fine."
