why does my neighbor do this?

i am not sure what precipitated this installation...at first i thought it was halloween, but it remained and then changed at thanksgiving...then christmas. did they clean out their garage, find this old wig head and not want to part with it? oh...its up-cycling!, i declared. but then she got a new sparkly outfit for new years. and, yes: red and pink for valentine's day, followed by green for the st. patty's celebration. thank god easter came and went, because this fantastic spring planting outfit appeared this week. oh, man: cinco de mayo is next.
