Sometimes, you will find that you are feeling a gap in your chest, a hole in your heart, something that you know you can never fill up no matter what you do, no matter how hard you try. There is a longing inside you that aches every single time you thought about the person you love, how that person used to be beside you every day, how you used to wake up seeing that person on the other side of the bed.
Or maybe you just miss how that person kisses you on your forehead before you say good night to each other. Basically, you miss everything about this one person whom you have made your world back then. But now, that person is gone and he is never coming back.
However, you can still express what you feel through these I miss you memes to say what you wanted to say to him.
