Never strip off your pajamas and then walk in to your own private bathroom in your own master bedroom at the back of your apartment in order to clean up before getting dressed. Otherwise you may find yourself standing naked in your bathroom as all of the children of the neighborhood congregate on your bed, right next to your clothes. You may then find yourself yelling through your bathroom door something like "Go out of the bedroom and close the door, go out now, I don't care what you're playing just get out, get out now, GO! LEAVE!, CLOSE THE DOOR NOW!!!!"
Don't even do this when your children are under the supposed supervision of their father since he obviously doesn't see anything wrong with letting everyone play in your bedroom while you are trying to get dressed.
