Answer:
What kind of table has no legs?
Die without me, never thank me. Walk right through me, never feel me. Always watching, never speaking. Always lurking, never seen.
We are five little objects of an everyday sort. You will find us all in a tennis court.
My first master has four legs, my second master has two. My first I serve in life, my second I serve in death. Tough I am, yet soft beside. Against ladies cheeks I often reside.
Has no feet, but travels far. Is literate, but not a scholar. Has no mouth, yet clearly speaks.
My days are numbered. What am I?
