I go around in circles, but always straight ahead. Never complain, no matter where I am led. What am I?
I am the kind of ant that's good at math.
Upon your lonely journey I accompany you, whether you travel through endless mountains or seas of blue. Wherever you go, I keep your place. Lost you're not, when I'm embraced. What am I?
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
