Why?

I don’t get it. I go out and buy all the good stuff – chicken, fish, veggies, sweet potatoes, fruit, nutmilks, nuts, granola – I mean all out. I spend three days preparing healthy, natural meals. My fridge is stocked with ready made meals packed with nutrition and flavor. So why is it that yesterday I went to my sister’s foraging for cake and ice cream and everything but the kitchen sink? Can somebody explain please, cause I just don’t get it!!
