Gingerbread House FAIL!

One of the annual traditions between my daughters and their 2 cousins is that of building a gingerbread house.  It's always a great time to see the 4 of them (ages ranging from 2 to 6) sitting at the table working together to build and decorate a gingerbread house.  Unfortunately things did not go so well this year.  Whoever the architect was in this group did not do their job!  The gingerbread house collapsed!

  

I know in the past the kids usually don't wait for the "glue" to dry on the walls before decorating the outside and it's never been a problem.  This year however, the walls started to slip right away once decorations were added.  If I had to guess, we had a different brand of gingerbread house and the frosting or "glue" was a bit more viscous than in the past, or in more common terms, less thick.  As a result, the walls slid apart before the "glue" dried.  Oh well, you win some you lose some.
