A friend of mine told me that when her daughter refused to stay on at school and do her A'Levels, my friend, her mother, didn't kiss her for a year. This woman said she was so furious with her daughter that she didn't kiss her hello, goodbye or nothing for a year. Seriously, that's some passive aggression! It has somewhat put me off this friend and seems a bit excessive to me. She said her daughter was devastated about this at the time.
