Hi there, here are some of my ideas below :)
Many were tortured in slavery. If a slave was refusing to do work they would be tortured half to death or to death. They would have whips and whip them with them. Some would try to escape and would be beaten or hung. Some were burned. In slavery it required long hours of work. In slavery the male or female would get up early in the morning and work all day, sometimes they would miss a meal and would be forced to work all day until the sun set. The men would be out in the field while the women cooked, cleaned, and probably made clothing for themselves and their masters.
People were bought as slaves at a young age, and they would grow up to work. If a mother/father was a slave and had a child, their child would be a slave as well.
Annabeth's actions in Chapter 18, when she distracts Cerberus with the red ball she stole, prove that she is intelligent and quick on her feet, always preparing. These are all traits of a daughter of the goddess Athena.
