Answer:
You do not want me when you donβt have me, but when you have me you donβt want to lose me. What am I?
A necessity to some a treasure to many I'm best enjoyed among pleasant company. Some like me hot some like me cold. Some prefer mild some like me bold.
I am black white and read all over.
Better touch me before you proceed to second.
I am perfect with a head perfect without a head; Perfect with a tail perfect without a tail; Perfect with either neither or both.
I go in hard, come out soft. Blow me hard and I'll make a pop. What am I?
