We have a frog in our house.
I have no idea how he got here.
He greeted us when we opened the door upon returning from our walk.
We tried to escort him outdoors.
He promptly hopped under our closet door and under our washing machine.
He just emerged, announcing himself by consistently bumpking into very solid, very metal doors.
He refuses to be caught.
I cannot catch him.
I am afraid of
...stepping on him in the dark of the night...
...chasing him back under the washer...
...finding his pathetic self dried up and shrivelled in the morning.
