the curious incident of the dog in the nighttime 2

I was very surprised when I found out that Christopher's mother wasn't really dead. It never occurred to me that a man as truthful as his father wouldn't tell his son that his mother moved somewhere else with another man. I thought that this was very selfish of him, and that Christopher had every right to know about the letters that his mother had sent him. Knowing that this is a true story makes it even more surprising. It's terrible that Christopher had thought that his mother was dead and had to live without her for a few years.But he dealt with this just fine and didn't make it overcome his life. It's terrible that this happened to Christopher.
