Wish houses

Out for a lunchtime walk I spotted these little houses dotted around on the grass, rocks, at bus stops and in the shopping centre. I am not sure where they came from but a wish was written on each one, 'i wish my house offer will be accepted' 'i wish my little brother will get well' 'i wish to win the lottery' and my favourite one 'i wish this awful hair dye will fade soon'!
