Climbing up the tower I looked down at a toiling nun. Feeling rather frivolous I shouted "Yoo Hoo!" I like to think that she didn't hear me for all the noise of her brisk scrubbing, or that she was listening to her favorite heavy metal band with earphones under her headdress, but a more probable cause for her non-reaction was that she thought (in Romanian), "What the heck? I wish that stupid tourist would shut his face. I've got work to do!" Regardless of what she thought, I did shut my face and continued up to the next level.
