Owen Williams and his wife befriended their octogenarian neighbor when they moved into their home in Wales three years ago.

When their daughter, Cadi, came along two years ago, their neighbor in the town of Barry, Ken Watson, became a grandfather figure, taking the time to drop off Christmas presents for her. Then Watson died in October.

On Monday, Watson’s daughter stopped by the Williams home with a large bag, and Owen thought perhaps she was on the way to take out the trash. It turns out, she was dropping off 14 wrapped Christmas presents her father had bought and wrapped for Cadi.

“The thing that stands out to me is how few people know their neighbors,” Williams said. “People are saying, ‘That’s so lovely. I don’t even know my neighbors.’ . . . This Christmas, take your neighbors a bottle of wine or a small gift, a token. Just say, ‘Hi.’ You can open a new world like we did.”
