Summary, You Were Wrong Being A Light Sleeper?

"Mary, you were wrong being a light sleeper." Said Sandra crossly, shaking Mary's arm. "Please wake up. This is the twelfth time I have called you. Don't make it thirteen. Thirteen is a very unlucky number."

Mary got up and rubbed her eyes. Sandra was already dressed in a multi-coloured shirt and jeans. "I am so sorry, Sandra. I don't know....I got a nice dream...so I just drifted off...."

"Well, go, brush your teeth and wash yourself." Sandra ordered. "Robert's office has provided us a car. Free travel!"

"That's nice to hear." Said Mary.

After Mary had washed up and a hearty breakfast, they locked the room and went downstairs. Robert was already waiting in the driver seat. Sandra sat in the front and Mary was at the back.

"The hospital is twenty kilometres from here." Declared Robert. "So, Mary or Sandra, if you have lost sleep, you can sleep for a while. It is always the driver who has to stay awake."

"No, I think I will stay awake." Said Mary.

"I think I want to sleep." Said Sandra. "I didn't sleep well last night." She leaned forward and whispered, "I was thinking about her. About our times together, how we enjoyed college life. It made me too anxious, actually."
"All right. Well some evenings, she goes to Yorkshire library. It's not literally in Yorkshire, just the name. Go straight, then left, right and there will little bend. Turn around that and there you are. Sundays...she goes to the church near Yorkshire library. And sometimes she goes to this old tea house south of the church. Forgot its name. Then...hmm...hah! She goes almost every evening to this place and attends talks about scientific stuff. The place is called....The Science Gallery. It's just this sort of gallery with working models, pictures and all scientific stuff. Mathilda loves science like anything. Then...that's all I know. Just check out these places she might be here. Maybe she wanted few days off. She's been performing a lot of surgeries,
