Tato and Mama gave me a home in Ukraine. Now they're under attack

They're not my parents, but after two years of living in Ukraine, they grew to become my Tato and Mama -- Ukrainian for "mom" and "dad."

Five years ago, they welcomed me into their home like a daughter -- now they're living under Russian bombardment, the sound of shelling punctuating every precious call.

Tato, a white-haired man in his early 60s, tells me on the phone he can see explosions from the front yard of their home in a small village outside the northern city of Chernihiv. Mama, who's a few years younger, sobs as she tells me they have no water, no power, and no safe way to leave.
