Use the key!

• When I arrive home in the night, the front door is usually open.  But when it is locked, I usually have to wait for someone to open it, because the door can be locked from the inside so that it can't be opened by key from the outside.  If I do try to use the key open the door in that situation, I will find I can't open the door and so have to undo what I did with my key before I can get inside  -- if someone does try to unlock the door from the inside then, I have locked the door on the outside.  Understand?  Any way!  Last night, I found the door was locked, so I knocked.  Tony screamed "use the key!" to solve my quandary.  The first time he has ever done.  His use of sentences is improving on an hourly basis.
