Answer:
I am an odd number. Take away a letter and I become even. What number am I?
Long and thin red within with a nail at the end.
I'm sometimes white and always wrong. I can break a heart and hurt the strong. I can build love and tear it down. I can make a smile, but more often bring a frown. What am I?
I'm not really more than holes tied to more holes; I'm strong as good steel, though not as stiff as a pole.
I have a hundred legs but cannot stand. I have a long neck but no head. I cannot see and I help keep your house neat and tidy.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
