This Mother's Day, it's easy to see what the pandemic has taken. It's harder to spot the gift it offers, because we have to cut through the exhaustion, the tantrums, the sibling battles and the homeschooling to receive it.  Time. Parents with grown children tell those with little ones there is never enough of it. Blink and they're grown. The relentless intrusions into your bed, your quiet time, your bathroom trips are over sooner than you think. One day the children will be gone. And many of them were, until the pandemic suddenly brought them home again. "We get to have them in a way that probably we're never going to have them again in our lives," said Nancy Colier, a psychotherapist and interfaith minister. "There's something incredible about the fact that they can't go anywhere. They are here. And so are we."
