My parents were stumped. What was wrong with me? I wasn't like anyone else's kids. Today, what I did would be familiar. Most Jewish communities and clans have seen the phenomena. It may not be as common as marrying non-Jews, but it's not as from Mars like rare and unheard of as it was in 1965.
Today's term for people like me, BT-baal teshuva, was unknown then. The same goes for FFB-frum from birth.
When I was growing up, I thought that all Jews were like myself. We ate all foods and in all restaurants. I didn't know that there was a Shabbat. If I went to shul, I wore extra nice clothes, but I didn't know that there were restrictions. We walked, because it was a distance we always walked, but I must have realized driving wasn't allowed, because the shul parking lot was closed. Only when I was thirteen and we moved to Great Neck was I exposed to an Orthodox synagogue, because that's the one we ended up joining. No, not from ideology, Great Neck Synagogue's Rabbi Wolf was very welcoming even to people who could barely pay a symbolic amount as dues.
Yes, the rest is history...
