Rav Yisroel Meir Kagen HaCohen, the Chofetz Chaim
“How delicious this food is!” exclaimed R’ Yisroel Meir again and again as he ate with apparent relish a meal prepared for him by his hostess.
“Could it be,” wondered those present, “R’ Yisroel Meir is praising something a mundane as food?”
It turned out that R” Yisroel Meir’s intention was to bring satisfaction to his hostess. Since a person who prepares something for another rejoices when his efforts are appreciated, R’ Yisroel are appreciated, R’ Yisroel Meir was expressing his appreciation.
