Shakespeare's Sonnets: Thy gift, thy tables, are within my brain

Thy gift, thy tables, are within my brainFull character'd with lasting memoryWhich shall above that idle rank remainBeyond all date, ev'n to eternity.Or at the least, so long as brain and heartHave faculty by nature to subsist,Till each to raz'd oblivion yield his partOf thee, thy record never can be miss't.That poor retention could not so much hold,Nor need I tallies thy dear love to score;Therefore to give them from me was I boldTo trust those tables that receive thee more. To keep an adjunct to remember thee Were to import forgetfulness in me.
