This makes me think of a good friend from college that I lost touch with, who recently committed suicide. I felt a significant amount of guilt, thinking about the fact that I could have very easily stayed in touch with him, despite not living anywhere close. Really made me think about people that I've had friendships with in the past that I may be able to reach out to and make a difference in their lives just by being the one person (or one of a few) that they talk to on a semi-frequent basis.
