Sometimes I fly as fast as the speed of light. Sometime I crawl as slow as a snail. Unknown until I am measured but you will certainly miss me when Iβm gone.
First I may be your servant's name. Then your desires I may proclaim. When your mortal life is over, I hold all your wealth within my power. What am I?
I begin your sentences. What am I?
I have palms but not on hands I offer foods from distant lands When at my peak you'll see me smoke I'm famous for my friendly folk My flowers grow and yet they lay There's fire where a man will play.
You do not want me when you donβt have me but when you have me you don't want to lose me.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
