best friends?

instead of doing my incomprehensible physics homework i tend to wander the internets; or in this case my facebook feed. i keep coming across the same note/quiz/thing done by different people, & this time i stopped to read one done by a good friend of mine. and for some reason it got me thinking, do people back home still think of me as a friend? i'm an insanely busy person with a stressful life, but who really understands that? i don't deliberately ignore people, but if someone's life consumes them and they fall off the face of the earth can you still consider them a friend?
