The ''with sharing'' keyword allows you to specify that the sharing rules for the current user are

considered for the class. You have to explicitly set this keyword for the class because Apex code

runs in system context. In system context, Apex code has access to all objects and fields---

object permissions, field-level security, sharing rules aren't applied for the current user. This

strategy ensures that code doesn't fail to run because of hidden fields or objects for a user.
