Saying I miss you shows that when the person is not around it leaves a void in your heart. There is a saying that distance makes the heart grow fonder, and if you miss someone then you want to shorten the distance that there is. I miss you quotes can help you remember why separation can be a good thing at times. When you have missed someone and then they come back the emotions that you feel can be very strong, and the longing that you have felt for the person may be visible. Make sure that you only use this phrase if you truly miss someone, because if it becomes the natural thing to say then the other person may start to take you for granted because of how often you repeat it.
