Q: in hello sexy pants does the line "At the clothing store, nobody tells you that the whole world is changing. At the grocery store, someone will tell you what changed is you" mean that when you focus on superficial things like clothing and how others think of you, you don't realise that you can't please everyone because everyones opinions always change, but when you focus on what you need, like food, you realise that you are always changing and can only please yourself? or am i just completely off? 
A: it's like a story (like from books, etc)
