The eye test

David leaves London and makes aliyah (emigrates) to Israel. As soon as he
settles down in Tel Aviv, he goes to see the local optician.
"I’m having trouble reading," he says, "maybe you could check my eyes?"
The optician agrees and sits David in front of a large eye test chart. "Can
you read the letters on the bottom line?" he asks.
"No," replies David.
"So how about the next line up?" asks the optician.
Squinting, David replies, "No, I still can’t read them."
"OK," says the optician, "let’s start at the top line. Read out the letters
please."
"But I can’t," says David.
"Are you perhaps a teeny bit blind?" asks the optician.
"Certainly not," replies David, "it’s just that I’ve never learned to read
Hebrew."
