When doors open and close

The past few weeks the doors in our house have started opening and closing properly. Winter must be right around the corner!

Let me explain. All year long (except the few months of winter) Bangladesh is very hot and very humid. So humid in fact, that the doors in our house that open to the outside become swelled with water and don't open or close without considerable pushing or pulling. I'd forgotten what it was like to close this door without using my shoulder and hip!
