We don't go to synagogue, we observe the major two holidays, but then only barely. They've worn a kippa a handful of times. Perhaps a very small baby handful. In a few years they'll have a bar mitzvah and won't know what it is. They'll grow up, get married and won't care whether they stand under a chuppah. They'll have kids who will grow up to know even less about their heritage. And that would be a shame.
