A reader writes... My girlfriend talks about nothing except topics relating to and interesting to her; I get no chance to speak about My day or My thoughts. When I do talk about My day, she seems to zone out. I've spoken to her and lately she's been trying to ask about my day, but it's always too late: I've forgotten everything except her story, her problems, her life. What can I try to get her to engage me in conversation instead of just talking at each other?
