RIDDLES FOR ADULTS

My voice is tender, my waist is slender and I'm often invited to play. Yet wherever I go I must take my bow or else I have nothing to say. What am I?

What can be touched but can't be seen?

What do geologists do on their free time?

What did the two volcanos say to each other on valentine's day?

What kind of running means walking?

I have four wings, but cannot fly, I never laugh and never cry; On the same spot I'm always found, toiling away with little sound. What am I?

I have a big mouth and I am also quite loud! I am NOT a gossip but I do get involved with everyone's dirty business. What am I?

What can be stolen, mistaken, or altered, yet never leaves you your entire life?

Until I am measured, I am not known. Yet how you miss me, When I have flown.

What am I?

Some try to hide, some try to cheat, but time will show, we always will meet. Try as you might, to guess my name, I promise you'll know, when you I do claim. Who am I?
