I am honored by your proposal and have given it much thought, but I must tell you that... to my own surprise, I have undergone what can only be described as a change of heart and I'm afraid I cannot accept your offer.
Zure proposamena ohore handia izan da eta arretaz aztertu dut... baina, nire harridurarako... nire bihotzak beste bide bat hartu du... eta, tamalez, ezin dut onartu zure eskaintza.
