You can see me, but I have no mass.
I am a chair, a dog, a lass.
You can move me, but cannot touch,
destroy me, though not so much.
I live inside and out,
but do not pout.
I am always present,
though not always pleasent.
Now the riddle starts to fly.
So tell me , what am I?
Third try... hope it's harder than the last one.
