UGH i know how oyu feel..... My inlaws live right next door and my grandfather-in-law knows no bouderies. He will just walk on in w/out knocking. I woke up one morning to find him standing in my room waking me up! What if I had been naked? I told my husband I just migh tbe that way one day and embarrass the hell out of himm and mabye it would break him. But I just started locking all my doors. And if the matinance man is'nt supposed to be in there w/out you then he should be warned or reprmanded for it by his boss. That's unprofessional.
