my daughter and her b/f would stop shouting and griping at each other

am i being selfish asking for a bit of respect here? i am so stressed, depressed and fed uptoday, now she is slamming doors and shouting and ranting cos the neighbours security light is shining into our house .... i told her they only just put it up and they probably didn'trealise it's shining in and all she needs to do is have a friendly word whenthey come in and ask them to re adjust it ..... anxiety levels going UP
