"It's a lot harder for witches to conceive.". Katarina added after what Rachel said.
"Conceive?.... But not everyone wants too." Sai could rattle off the names of some women who swore off marriage. Of course, from his past life.
"Not being able to and not wanting to are different. The choice seems easy to make as one would naturally enjoy a longer lifespan but at the end of one's life, very few would be there. A long life can be quite dreary at times."
Rachel said that with a faraway look and everyone agreed not to mention it.
"And also, witches are subjected to multiple restrictions which can only be lifted by becoming stronger. It is often said that a witch's power can be judged by the number of restrictions she has left."
Rachel and Katarina wee wain sync as they offered explanations to Sai. It was also to the point that Sai started wondering whether they were mother and daughter.
