Mourning memes

One night, a girl said to her family, "Goodnight Mommy, Goodnight Daddy, Goodnight Grandma, Goodbye Grandpa." The next morning, her grandpa died. That night, she said, "Goodnight Mommy, Goodnight Daddy, Goodbye Grandma." The next morning, the grandma died. The dad started to fear for his life because he was next. That night, the girl said, "Goodnight Mommy, Goodbye Daddy." The next morning, the dad woke up and he was perfectly fine, but when he went into the kitchen, he saw his wife crying. When he asked her what's wrong, she said, "The mailman died."

Why did the family get mad at the boy for eating at the funeral?

While trying to season his food, he mistook his cremated grandfather for salt.

"I'm sorry" and "I apologize" mean the same thing, except at a funeral.
