Tameka is leaving her office following her last appointment of the day. As she approaches her car in the parking lot, she sees Danielle, the mother of one of her clients, pull her car directly behind a parking space, blocking in Sam, the child's father. Tameka observes Danielle exit her car and begin yelling at Sam, who remains seated in his car. Tameka is subpoenaed for a court proceeding when Sam files for a restraining order against Danielle. Tameka should expect to testify:

A) About what each parent has told her about the other and to then offer an opinion as to whom is at fault for the incident

B) That Sam had to have done something to aggravate Danielle as that behavior was out of character for her

C) About her treatment with the parties' child

D) Strictly as to what she actually observed and heard
