[单项选择]We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. "Did Jerry really care when I broken up with Helen " "When I got that great job did Jim really feel good about it, as a friend " "Or did be envy my luck " "And Paul-- why didn’t I pick up that he was friendly just because I had a car " When we look back, doubts like these can make us feel bad.
