My girlfriend is a social worker and works at a primary school. These are some responses I have had to "how was your day":

"Today a girl was raped by his grandfather. We suspect he's also his father."

"A 10-year-old boy commited suicide. I went to his family's home and they still had the body lying down on the living room."

"A boy has told us that her mother every night gets money from men to 'spend time' with her sisters. Today I went to court to try to take the girls away from her, but the judge allowed her to keep them."

I don't allow myself to think I have bad days at work.
