When taking laundry down to the basement, don’t shut the back kitchen door all the way, it might be locked.
Then you might have to try to get your two year old to come and try to open the door for you.
Of course that will fail, because your two year old thinks you are trying to take him away from legos and will tell you no.
Assessing the situation, thank God that you actually got dressed this morning, walk out in your sock feet and try the front door.
Then make another note to kiss your husband when he gets home from work because he left the front door unlocked when he left for work.
