1969. My parents started studying because of rooming work.
One of my dad's employees was a witness and mentioned to him that there was to be a big international convention in NYC and would he be interested in putting up a visiting family from another country.
My dad said, well, I don't know. How long is the convention? 5 days. So my dad figures family (2 adults and 2 children) arrive the day before and leave the day after.
Wrong. 2 Adult women and 2 teenagers (17 and 19) stay for 3 weeks.
*Heavy sigh* from both my parents. OK our house is your house. We will share our food and our home with you but NO PREACHING.
And they didn't preach a single word. For 3 weeks. My parents were baptized at the next district convention in 1970.
-Aude.
Edited to add: OH! the fun part that I remember was weeks and weeks leading up to their arrival my brother (6 y/o) and I (9 y/o) were imagining where they would be from. What language would the speak? How would we understand them??? Two days before the convention we got our answer: England!
My brother asked: "oh good! But what language do they speak??"
(umm actually, *I* asked that question, but i didn't want y'all to think I was that stupid....!)
