From the WT book "Children" published in 1941, pgs. 366-367:
Armageddon is surely near, and during that time the Lord will clean off the earth all that is disagreeable. Then, by His grace we shall begin our life with a greater vision, and prolonged joy...From now on we shall have our heart devotion fixed on the THEOCRACY knowing that soon we shall journey forever together on the earth...We can well defer our marriage until lasting peace comes to the earth. Now we must add nothing to our burdens, but be free and equipped to serve the Lord...Eunice, my decision is made. I shall shun politics, religion, and commerce, and I shall avoid the cities...Our present duty is plain. We must now be witnesses to the name of Jehovah.
A 10 year old child reading that book would now be in his or her mid 80s.
