Moshe calls his mother and asks, “How are you?”
“Not too good,” she says. “I’m feeling very weak.”
“Why, mother? ”
“Because I haven’t eaten in 23 days,” she says.
Moshe replies, “That’s terrible, mother. Why haven’t you eaten in 23 days?”
She answers, “because I didn’t want my mouth should be filled with food if you should call!”
