Long-distance relationships are painful, because it's hard to say goodbye when they meet, and they feel disappointed because they can't cling to each other, but they are the happiest. Because of that courage, that trust, that persistence. Whenever you are alone, think of someone who is holding on to you and sharing the burden with you. People who are not in a long-distance relationship cannot feel it. That kind of warmth, that kind of silent communication, and unconditional trust is the greatest happiness!
