Yes, it does. I despise people with cosmetic surgery, you're just ruining/mutilating your natural body. Nose surgery can make it harder or even completely block breathing through your nose, is that what you want? How about 50 years down the line, do you realise how ridiculous you will look? As the rest of your face ages normally, your plastic looking nose will stand out like a sore thumb. Why do you care if your nose is too wide? NO ONE cares, everyone's too busy thinking about themselves to think "hmm, that random persons nose is 3mm too thick".
By getting cosmetic surgery, everyone that knows you (friends, family, coworkers, peers etc.) will just think of you as a vain, shallow, self-conscious and pretentious.
Don't get cosmetic surgery, you will regret it when your mind has matured.
