A goodbye and thank you

Why is it so difficult for some people to say goodbye? Don't they understand that nothing good comes from just disappearing from somebody's life. Today I realized that a good, old friend has left Finland, probably for good without saying anything to me. Must say it hurted. I guess that person thought I would read about it on FB, but we haven't been friends there for some time now thanks to differences in opinions and ways of thinking..after all, one shouldn't rely on FB too much as a source of information. It's a pitty that people don't let you know things anymore, and just assume that you read about it on FB. Anyways, I want to wish that person all the best in the world. Thank you for being such an important part of my life and for making me grow so much. I believe only you and me can know what our relation was and in my opinion will be forever. I hope to hear from you soon again my friend.
