The question:

I am tall and strong, yet utterly powerless.

I am silent and speechless, but I may still speak to you.

I don't wear clothes, but dress up a couple times a year.

Some notice me, some hug me, some don't even want me.

I can vary so much, yet still be the same thing.

You live in me, write on me, even breathe me.

WHAT AM I?????
