Biff continued to wander the streets in search for a new identity, until he entered the Sanders house and walked to the room belonging to Tiffany. She was the best friend of the former Sarah McMillan and had the reputation of being the school slut, which was completely justified.
Tiffany had already woken up by the time Biff entered her room. She appeared to be talking with someone on her cellphone. It was probably one of her friends, from what Biff was overhearing. He never understood what compelled girls to talk so much, and they never talked about anything important.
As Biff walked past her bed and straight to her closet, Tiffany made no notice of him. After opening the closet, he took out some of her clothes and took off his own underwear. Being a slut, Tiffany would have enjoyed seeing that, but she continued to not notice Biff's presence.
He put on a silky thong, but no bra. Tiffany rarely wore one. And then he put on a pink tube top, a short white pleated miniskirt (so short that people could see his underwear, if he bent over even slightly), and a pair of pink 4-inch heels. Obviously, Biff had never worn heels before, but they didn't seem to be a problem for him. He easily moved around in them.
He walked to Tiffany's vanity and picked up a tube of pink lipstick. And as he applied it to his lips, Tiffany dropped her phone and mindlessly left her bedroom. Then Biff picked the cell phone up and continued Tiffany's conversation.
"Yeah, totally," Biff said, answering a question he hadn't heard.
