I was virtually a born-in. Not quite but almost. One parent became a jw when I was 1 year old and the other when I was 11 years old.
The highlights of my youth were the extremely rare non-jw things my parents allowed me to do. School camping trips (each one week long) at ages 10 and 11 and 14.
Even then there was no Xmas or birthdays and I remember vividly dreading whether I might be asked to salute a flag. Here's why.
In England no one outside the armed forces or at remembrance day salutes in the presence of the national flag.
But ... I was brought up on a diet of Watchtowers screaming that JW kids should not be forced to salute the American flag and so when I went to school camp we used a Scouts' (also forbidden for jw's to join because of its links with the Church of England) camp site on the south coast of England. Right in the middle was the Union Flag on a pole.
So come evening when 100 normal kids get their hot chocolate and sit round the fire and the flag is "struck down for the evening" I am dreading being the only one not standing and saluting.
Except of course, being laconic Brits the flag was dropped with no ceremony whatsoever and put away to be raised the next morning, again with no ceremony whatsoever.
Phew! Another jw test passed with flying colours! (Just not flying colours being saluted)
