Mistress

After Biff flunked math, he went to visit his father in the summer. Willy was staying at a hotel in Boston at the time. Biff entered Willy’s room and Willy told his mistress to go hide in the bathroom, and so she went in there.
Biff had no idea that there was someone else in his hotel room. Then, Willy and him were talking about how Biff flunked math. Biff wanted Willy to talk to his teacher to try to help. Willy told Biff that he would, and Biff was complimenting his father on how he was good with people.
After they talked for a while, Biff started to hear noises and laughter in the bathroom and he asked his dad if someone was in there. His father denied that there was someone there and made up the excuse that it was probably the people in the next room. Willy was pretty nervous that Biff would find out so he kept trying to push him out of the room, like telling Biff to go tell the clerk that he was about to check out. But finally, the mistress asked if she could come out because there was a bug in the bathroom. Willy immediately freaks out and tells her to leave and makes up an excuse about her being from next door and taking a shower there. Biff obviously doesn’t buy into the excuse for the naked women in his father’s room.
Biff is really upset and starts crying and changes his mind about wanting Willy’s help. He says he’s not going to U. of Virginia. Biff calls his dad a liar and a fake and yells at him for giving the woman his mom’s stockings. Willy gets really defensive and gets mad at Biff about it. He even says he’ll whip him if he doesn’t obey Willy. Biff runs off. Biff has gone from idolizing his father to thinking he’s a fake and a phony. I believe that this is definitely why their relationship is so rocky in the modern time.
