In "Ender's Game", how does Ender interpret his parent's reaction to the loss of the monitor?
Ender was trying to deal with the trauma of the "monitor" being removed from his neck after having it implanted three years prior to the novel's start. His brother is beating the stuffing out of him, and Card writes, " Mother came home and commiserated with Ender about the monitor. father came home and kept saying it was such a wonderful surprise, they had such fantastic children that the government told them to have three, and now the government didn't want to take any of them after all, so here they were with three, they still had a Third... until Ender wanted to scream at him, I know I'm a Third, I know it, if you want I'll go away so you don't have to be embarrassed in front of everybody. I'm sorry I lost the monitor and now you have three kids and no obvious explanation, so inconvenient for you, I'm sorry, sorry, sorry."
Ender is convinced his parents are embarrassed because they have 3 children and Ender is the third. The government had given them permission, but now that he seemingly doesn't qualify for the program, he feels they wish he was gone.
