Did not drink for three consecutive days
Did not return in the middle of the night
I want to do something healthy and meaningful.I like climbing mountains somehow recently
Try to regain the work that has been lost for half a year
It's been a long time since I read a book
After looking at the books where they were placed
they were almost moldy.I happened to see this book that has been with me for several years
This book also passes through many cities
Many journeys.This is an extraordinary book
always there.?Did not drink for three consecutive days
