I think singleness has loads of benefits. And I think young people would benefit from spending some of their adult years single and free. Time taken to get to know yourself and live for yourself is invaluable.
But, WT world encourages a weirdness to singleness. No dating, no flirting, no leaving home or getting an education. Spend that youthful energy "promoting kingdom interests."
And that is what makes what should be some of the best years of your life a total dud.
