You will always have a person to walk alone for a lifetime. No matter what your current friend is your upper bed. The classmates are still what others, you graduate, you leave those people walking on their own way
I don't want to be with you, just everyone is walking. There is no choice. There is only a temporary Tongger. In the next time, I only keep in touch with dear friends, but I'm too deep.
So only if you can be responsible for yourself, you can't do it.
