It's a boy

"This place is great," Penny remarked as the nun walked her out of the building. They passed several rooms filled with bright, happy children. Their adorable laughter and voices filled Penny's ears. 

The nun chuckled and nodded. "It is. This place has been here for a long time, after all. We had helped hundreds, thousands of children."

"Oh?" Penny raised a brow. "I didn't know this place has been here for a long time."

"It is not as high profile as other orphanages, but it's been here for ages. I was raised here, Mrs. Granger," the nun said with a hint of pride. "At one point, I was just like these children—abandoned, unwanted. But thanks to the teachers, the sisters, the sponsors, and everyone who gave us everything they could, I decided I wanted to be part of this orphanage's mission. Many of us grew up here, including some of the teachers you've seen today. That's why we understand the children better than anyone."
