Linda and Yves Aubry helped a 20-year-old Syrian man when he knocked on their door saying he was hungry.
Linda, a Roman Catholic, said: "He said in English he was hungry.
"As I didn't know him I said: 'Give me two minutes and I'll make you something.'
"I closed the door, because I was a little bit afraid.
"But I didn't ask myself any questions, I just responded to his need.
"I don't know why I did - I just did.
"It was the natural thing to do."
Linda helps and her husband help other volunteers teach French to migrants and work in the make-shift hospital, together they hand out food packages in the Calais migrant camp.
Sayid, not his real name, fled Syria and arrived in Calais in the summer of 2014.
As the weather got colder the Aubry family invited Sayid to live with them: "We came to the decision as a family, and decided that we would take care of him."
She said that "One day he came to the door and he looked really desperate.
"He'd become really thin and he was crying.
"He told me he couldn't do it anymore."
After living with the family for a period of months he made it to the UK one evening and called to let them know he had arrived and was in an asylum application centre.
Linda said: "When he left, it hurt.
"I was scared for him."
Sayid arrived in the UK but discovered his brother had already left for Canada.
His application for asylum was rejected.
Linda said: "If I find myself in the same position... I would do the same thing again.
"I wouldn't even hesitate."
