memory

Memory People come and go in your life but do they ever REALLY leave? Are they a memory or a peice of who you are today? If you find yourself missing people in the past, why didn't they make it to your future? Is it because we change or because we are all so busy with life and ourselves that we don't make the extra effort to reconnect? I  feel like there are so many people I care about and think about but can't seem to find the time or energy to hang out with them...or maybe I just need to make more of an effort. My point is, do you think that certain people are in your life for a purpose because you placed them there or because fate and God's plan comes into play? Just a random thought...
