While there are 50 ways to say goodbye by Train, some people just walk away with no goodbye. Maybe, they are not good at saying goodbye. Whatever the reason is, still another way of saying goodbye is just walk away.
When someone walked out of your life without a word of saying goodbye, you hold on, and the hope of hello never die. You deny.
You used to share your failures and little achievements then you just walked away. No goodbye. Went through a lot of low and bad times and you weren't there anymore, guess is, you really don't care anymore. That is goodbye.
