Peter was still feeling mostly normal by Friday, though he was starting his radiation therapy on Sunday and he knew he wouldn't feel normal once that began. In fact, he was most likely going to feel absolutely shit, so he wanted to take advantage of his health while he could. While he had it. Which was why he was headed to the store to buy lots of pie. With a beanie on his head to cover his odd bald spot. And luckily for Peter, his daughter was there to inform him that was not a good idea.
