Escaping Hotel California

You grab one of the fancy vases and throw it with all your strength at one of the large windows. Water and petals splash everywhere, but nothing but a minor scratch is left on the window. You reach for the next best thing to throw, a heavy wood chair. Unfortunately, it’s weight is hard to handle and your throw is even less successful than the first time. Seems that this window has bested you, throwing things was probably a wrong choice.
