Hello Fer: As far as I can see, Shall is often in the context of a request to another person, or even Speculation asked of one's self. For example: (To some person in authority) "Shall I remove the table settings? "Shall I put the equipment away?" "Shall I go to lunch now?" Using Will in these questions is an awkward use, in place of Shall. Will is frequently used as a Personal DECLARATIVE. As in when I declare what I will do, rather than ask of someone else what I should do. Examples " I will remove the table settings." "I will put the equipment away" "I will go to lunch now." Of course, Shall can also be used as a declarative, as follows. " I shall remove the table settings." "I shall put the equipment away" "I shall go to lunch now." It is more common to use Will however. That is what you will more often here in English use.---Warm Regards, Bruce
