Riddles

How can you lift an elephant with one hand

If a boy is slapped by his mother and his father which one hurts the most

Where does success come before work?

What is so fragile that saying its name breaks it?

What can be measured but not seen

What has a head and a tail,but no body

Whats yours but is used often by your friends and family?

I always drive my customers away,whom am I ?

What goes up but never comes down?

What is always in front of you but can't be seen?
