Excerpt:

When she tried to put away the groceries, Fern found the crisper drawer of the refrigerator was already jammed with unidentifiable greens in various stages of decomposition. They could only belong to Phil, who she found sprawled across one of the weathered, splintery Adirondack chairs at the far side of the lawn. He didn’t seem to hear Fern, although she repeated his name several times. Finally she touched his shoulder. He gave a little jump, then squinted up at her through his orange-lensed sunglasses. “Whoah!” he said.
“Sorry,” said Fern. “I didn’t know you were sleeping. I just had to ask you about this.” She held out a plastic bag full of a partially liquified green substance.
Phil stared at it. “Hang on, hang on,” he said, putting two fingers to his forehead. “I know I know this.”
“It’s not a trick question,” said Fern, slightly irritated. “I found it in the fridge. I wasn’t sure if it was yours.”
“Oh!” said Phil. “Yeah. It’s watercress. I was going to make some soup.”
“I think it already is,” said Fern. “What about this one?”
He took the bag and examined it mournfully. “Oh. That was the stinging nettle shoots.”
“Stinging nettle?” said Fern. “How come it was it in the fridge?”
“I was going to eat it,” said Phil.
“You were going to eat stinging nettle?”
“Yeah,” said Phil. “I’m teaching myself to forage for vegetables. Nettles are totally healthy. You can use them to make salsa. Or pesto. Or . . . salsa? I can’t remember.”
“Okay. Well, I think it needs to go, too.”
Phil was still holding the plastic bag reverently in his cupped hands. “People have totally forgotten how to see all the incredible bounty around them,” he said. “Did you know everything your body and your spirit needs to heal is right here? Like, do you know what the truly, one hundred per cent best cure for hayfever is? Locally-made raw honey.”
“Wow,” said Fern. Phil had to be stoned; there could be no other explanation.
“You should try doing this sometime: just go out into nature, lie down and pick a plant at random, and then like identify it and study it. It’s amazing,” he said. “Amazing. You will automatically be drawn to the plant that has healing properties for you.”
Fern gave the bag a tug to get it away from him. “Yeah, that’s cool. Anyway, I just wanted to ask you what was going on with these.”
Phil gazed at her, blinking kindly. “You know, you’re an amazing person.”
“Thanks,” said Fern, awkwardly.
“Wait -- what was the last thing we were talking about?” he asked.
“Don’t worry about it,” answered Fern, turning to go back to the house. But Phil clambered up out of the chair and shambled after her.
