double-front door at their apartment - and flowers?

[Ren&Stimpy]

Is that "standard" treatment to have two doors back-to-back?

Also, what's up with all the flowers? Today a lady showed up - wearing a huge winter hat - and delivered something to Nelly and took pics of her holding a boquet of flowers, then a pic of her and Bodgan with the flowers, and now I see flowers in the window ledges..... perhaps Nelly's birthday?
