The passage states, "His friend tries to follow his instructions, but halfway through she cannot remember the next step."
Titus needs to slow down with his instructions since that person cannot do every step all at once as quickly as he is telling her what to do. He needs to slow down and pause once in a while to check that his friend actually understands what needs to be done.
The passage also includes, "His friend is able to complete the next step, but she is stuck again at the following step and becomes frustrated."
