Unlucky 13

When I was a child, I had a silver "13" on my charm bracelet, so I grew up thinking that it was a lucky number. Of course I couldn´t understand when I heard or read that hotels don´t have 13th floors or rooms with the number 13. It wasn´t until tonight that I DID understand - just have a look at this postcard for this week´s SPA challenge ... I think I´d rather check in No. 14!
