Women seem to do that. Bringing old situations up is a way of exerting power and a way of exerting influence. It's a form of guile that their mothers teach them since they don't have strength and they are taught to not directly confront a situation. Heather tries that diminishing trick with me sometimes-- I just ignore her shit and she gets the message real soon. She once asked me why I didn't do something --- I just said " I don't want to do it that way" and didn't smile. She just looked at me and I think was fuming BUT didn't dare say anything--- she knew I was ready to "go downtown!"
