I am the black child of a white father a wingless bird flying even to the clouds of heaven. I give birth to tears of mourning in pupils that meet me even though there is no cause for grief and at once on my birth I am dissolved into air.
At night I come without being fetched, and by day I am lost without being stolen. What am I?
I am enjoyed by some, despised by others. Some take me for granted, some treasure me like a gift. I last forever, unless you break me first. What am I?
Soft, hairy, from door to door. I am the pet that always stays on the floor. What am I?
