FACEBOOK Challenge P/B day 5

I was challenged, by @Sónia Martins, to post a black and white picture once a day for the next 5 days, every day when I post a black and white picture
I need to nominate someone else to start the challenge.
I nominate @São http://saodiasassim.blogspot.pt/   to do the challenge.
This is day 5:  I could not choose only a picture >
