"It has come to my attention that the black iphone 5 is very prone to scratches and looks terrible within a few days."
So you're saying you see no indicators of a person saying a black iPhone 5 is so prone to scratches it looks terrible within a few days being a bit, shall we say, "over the top"?
A person who is obsessing over looking at his iPhone every day to find scratches is showing clear signs of OCD. Compare it to a cold, if you had cancer. Does it become clearer now?
No you are wrong. For OCD you need obsessions and compulsions. It is an anxiety related disorder. Compulsions fuel the anxiety. Just because someone is obsessing over something does not mean they have OCD.
Most people at one stage or another could identify with some signs of OCD.
Again I am telling you objectively that you are wrong. Move along now.
