shall, will
shall (SHAL) (verb)
1. This element is now mostly restricted to two situations, for interrogative sentences requesting permission or agreement: "Shall we go for a walk now?"

"Shall I open the present now?"

2. Shall is used in legal documents, in which it indicates a duty or responsibility: "This tenant shall obtain the landlord's permission before he makes any changes to the property."
will (WIL) (verb)
With minor exceptions, will has become the universal word to express futurity; regardless, of whether the subject is in the first, second, or third person: "My friend and I will be arriving in town early this evening and he will be driving the car."

Grammar rules formerly had the following formats which now are generally no longer utilized!

Simple Futurity

First person: I shall (s); we shall (pl)
Second person: you will (s); you will (pl)
Third person: he, she, it will (s); they will (pl)
Determination, Promise, or Command

First person: I will (s); we will (pl)
Second person: you shall (s); you shall (pl)
Third person: he, she, it shall (s); they shall (pl)

"The artificial distinction between shall and will to designate futurity has neither a basis in historical grammar nor the sound sanction of universal usage."
