I think that's for the players to decide, or the characters themselves.<br/><br/>I believe if we are all friends when we were kids and kept in touch (hanging out, play dates, etc) then I don't see why they wouldn't keep in touch as they grow older with emails and instant messenger or letters and phone calls. Unless the character themselves loses contact or stops keeping in touch would they not have any communication with each other. I know, Ophelia would try to keep in touch with all of her friends whether it's a phone call or sending them post cards, letters, emails.
