DEAR ABBY : One of our co-workers doesn’t want to be a closer friend even though at work we say we love each other. We want to take the friendship to a deeper level, but she hesitates when we try to hang out outside of work. She has a mansion that many people in our office have seen, but she hasn’t invited us over. She’ll only go to the movies with us. We are worried it is because, in a movie theater, we can’t talk to her. Are we getting mixed messages or coming on too strong? — GIRLS AT WORK
