So today, mine human beans put a blocking thing in the hallways at the tops of the stairs. I do not unnerstand why it is there. It do make it impossible for me to get by. But maybe one day I might be able to hop over it, just like mine Fergiemum http://paddingtonbear12.weebly.com/fergiemum.html ... I do be a Portuguese Water Dog after all ... and Portuguese Water Dogs do be gooder hoppers!!!
