my brother gave my parents a little house he made of cardboardand made a roof on it using money(he folded each bill to be a shingle..) and folded some to be windows...he know how much the roofing materials would cost,and windows.and did that and was more then willign to do the roof for her..(he knows what hes doing). well the bad part was she LOVED the gift ..thought it was so wonderful that she refused to take it apart..!!!!!and never did the windows...and only did the roof when it eventally leaked bad,
