I agree there is no need to write a letter. I have three brothers, who are much older then I am. They got baptized as teenagers, and have been inactive for about 23 years. Some congregation do let you fall through the crack. No one ever checked on them, to see what was going on. They still live in the same area. They still beleive, but it is if they were never baptize.
They don't go to church, but they do their own thing, Holidays, birthdays. I still talk to them. My mother was inactive for about 16 years before I got her to come with me to my new congregation, she loves it.
