All those who descended from Yaakov were seventy souls...(Shemos 1:5)
At the end of the Friday night seuda, everyone waited patiently for dessert. “Does anyone not want ice cream?” asked Shoshana as she took the ice cream container out of the freezer. The room was silent.
“I guess everyone is having ice cream!” said Shoshana and proceeded to count the people at the table to know how many bowls of ice cream she should bring to the dining room, “One, two...”
“Stop!” screamed out her brother Yonnasan, “You can’t count people!”
“Oh, you’re right, Yonnasan! I completely forgot that we can’t count Yidden,” said Shoshana. Then she thought for a moment and started counting everyone again: “Aleph, Beis, Gimmel...”
“One second!” said Yonnasan. “I am not so sure if counting using letters is okay either!”
Question: May Shoshana count the people at the table using letters?
