Normal individuals do not stalk others. However, there is no evidence that people who stalk have a mental disorder. 90% of stalkers are men and generally stalk at night, but are known to also stalk their victim during the day and may show up at their school or workplace. Stalkers can be anyone from a friend; acquaintance (someone you have met briefly); a former boyfriend/girlfriend; spouse; coworkers; a complete stranger that has admired you from afar, or even someone you may have gone out on a date with only once or twice.
