2. Narcissism: This kind of person always thinks he is beautiful or handsome, and likes to look at himself more if he has nothing to do. See other people's appearance, always compare yourself.
3. Habit: This kind of person doesn't know what to do when he is bored! Take a mirror with you! It has become a behavior habit to take pictures when nothing happens.
Always looking in the mirror is a mental illness, although it is not very serious and will not cause any terrible consequences, but it also needs more attention.
