Why does Caesar say he wil not read artemidorus' letter first? how is this part of the posture he has taken

he wants to read letters that are closest to him last

Explanation:

In Shakespeare's "Julius Caesar," the protagonist refuses to read Artemidorus' letter, which warns him about Brutus, Cassius, Casca and the rest of the men in the Congress. The reason is that they are planning a conspiracy against him and his life is in danger. However, Caesar ignores the man and wonders whether he is insane, since he intends to make his petition in public instead of in the Congress, as Cassius then tells Artemidorus:

"ARTEMIDORUS

Oh, Caesar, read mine first, for my petition affects you more directly. Read it, great Caesar.

CAESAR  

What touches us ourself shall be last served.

CAESAR

Whatever pertains to myself I will deal with last."
