Barcelona Spain: Windows, balconies, and more

I was walking along a side street in Barcelona. I like taking photos of windows and doors for some reason that is hard to explain. Here is an apartment house. The people on their Juliet balconies would be on the Third Floor - as the numbering system goes Ground-One-Two-Three-Four. Their Third Floor would be the Fourth Floor in the U.S. The children are getting some outside time.  This is not to say that children do not have plenty of parks and safe areas to play, but in any urban area there are few backyards.
