Guess what

So... I dyed my hair on Saturday and my mom is all upset about how it turned out. The photo I showed to her before going to the hair salon was brighter, and she said it looks great, so I thought she gave me a permission todo so. In spite of the facet that I chose to make my hair darker than the photo I showed to her before, she got so angry about how bright it became. If my parents were paying the fee, I would have to follow what they say, but I paid for it with my money. Why do I still have to be scolded for doing whatever I want with my money? (I am sure it's not illegal to dye my hair 笑)
