I'll admit from the ages of elementary till university a lot of my childhood friends break off into various paths.
It's just reality and some(if not most) I lost contact with. Although when you do catch up with people from those
days it is a...almost serial feeling. For me it's just good to catch up on both bad and good memories after years
of not talking, and then seeing how much a person has changed. For example I met up with a girl from the days of
kindergarten and back then I was extremely short until mid-high school. After our graduation of elementary we separated
and re-met 9 years later. She was dumbfounded on the person that I've become, from someone short, cute and shy to
someone tall(in her eyes I'm only 5'10 xD), thoughtful and outgoing.
So to wrap this all up, you might loose contact for a while or even years. However, if a relationship still exists and
you can at least remember a face and name, I'm sure it will still exist. Add that person to facebook or something
just in case. You'll probably look back in a while and say, "Hey...I remember him/her. Maybe I should give a
call and catch up with him/her. =)"
This is on a friendship situation though, anything else...well that's out of my bounds to say. xD
