In two words, it is separation sorrow
Separation is always something that we don’t want to face in life, but it is inevitable and happens frequently.
When I say goodbye to you, I may say goodbye with force or with gentleness. With force, I want to convey all my reluctance to you, but with gentleness, I don’t want you to know my sadness and feel sad for me. As long as we get together, there will eventually be a time to part. The reality must be faced. Staying any longer will only make the longing that takes root in the heart entangle the steps away, and make the tears that want to cover up the flow in the heart fall out of the dry eyes - years, after all, cannot be stopped; Time will never stop for anyone's reluctance. So, I can only wish you well. I wish you will be happier and more enviable when you are about to go far away. I will deliberately ignore the distance between the ends of the world, just to win the heart-to-heart connection with you at this moment.
If there are no flowers to send, I still have to say goodbye. The pins on your clothes are not just my hoarse blessings.
