"I was mistaken", Constand said.
Montgomery County District Attorney Kevin Steele pinched the bridge of his nose and stared at the table as Constand gave the response.
The real underlying argument that the defense is making, though, is that the sexual encounters that the women have been sufficiently mendacious or manipulated enough to call assault were actually consensual.
He noticeably shook his head when Constand described the alleged sexual assault in detail, claiming that Cosby undid her trousers, put his finger in her vagina, and placed her hand on his penis as she was under the influence of drugs and alcohol he provided.
Cosby was not charged with any crimes at the time of Constand's original allegations, but he did settle a civil suit with her out of court in 2006. "And I felt him take my hand, place it on his penis and move it back and forth", she told court. "This man was a trustee at Temple".
He also suggests that Gianna Constand and her daughter travel to meet with him to discuss his proposal.
Constand was direct and polite under cross-examination, even when Agrusa's questioning grew pointed and accusatory. Or succumb to her defense portrayal as a woman who encouraged Cosby's romantic overtures?

Agrusa contended that the advances Cosby made on Constand on two occasions - touching her thigh one time, and attempting to unbutton her trousers and pull down her zipper another - signaled his romantic interest.
"You knew Mr Cosby was married, right?"
"I don't really remember how dim the lights were, but I did have to eat my dinner", Ms Constand said. Cosby said he would mail her the name of the prescription, she testified, but never did.
In that phone call, Cosby asked the mother to get Andrea on the phone and explain what happened because "he wasn't going to tell the truth", Gianna Constand said.

After Raabta's trailer released in April, Twitter was also quick to notice the similarities between the two films . Less than 24 hours before the release, the court has finally thrown out the case filed by " Magadheera " makers.
Another potential problem for Constand is the fact that there had been some sexual overtures by Cosby before the night of the alleged assault.
The situations became questionable when it was clear that Constand would return to his home after denying his attempts.
"She could go to school", he said. "She viewed him like a father", she said.
Returning to the phone logs, Feden pointed out that in nearly every case the calls Constand placed to Cosby came after she had checked her voicemail - a pattern that bolstered her claim she was merely returning messages from Cosby, the prosecutor said.
"They were good friends".
The mother testified about two phone calls she had with Cosby in January 2005, one lasting more than two hours and another, much shorter call the next day.
His lawyers have tried to poke holes in Constand's story, citing differences between her courtroom testimony and the accounts she gave to police and in a lawsuit in 2005. She was embarrassed to even tell me. She did not see Cosby before or after the show, she said, but she gave Cosby's aides a gift from her brother. Cosby then engaged in sexual activity with her when she could not resist, she testified through tears.
"No, he was sorry for what he did", Gianna Constand shot back.
Some 60 women have come forward to say Cosby sexually violated them, all but destroying his nice-guy image, but the statute of limitations for prosecution had run out in almost every case.
Her testimony is central to the case against the star of The Cosby Show, one of the most popular shows in the history of television.
Bill Cosby arrived for the third day of his sexual assault trial accompanied by one of his co-stars from his 1970s movie run. Each charge carries a maximum sentence of 10 years in jail and a US$25,000 (S$34,500) fine.
