I Don't Know

I have built a tower Right next to your name Now I have to decide Should I live in the tower or should I break it down Oh i don't know, i don't know Oh i don't know, i don't know I have ridden a horse Through the whole desert Should i keep on riding this horse Till i get to the water or should i just let myself die? Oh i don't know, i don't know Oh i don't know, i don't know
