Bella the matchmaker goes to see Abe, a bachelor for many years.
“Abe, you mustn’t wait so long. I have exactly the wife you need. Just say the word and you two will meet and be married in no time at all.”
“Don’t bother”, replies Abe, “I’ve got 2 sisters at home who look after all my needs.”
“That’s all well and good” says Bella, “but all the sisters in the world cannot fill the roll of a wife!”
Abe answers, “I said ‘2 sisters.’ I didn’t say they were my sisters.”
