You can no longer get away with having wishy-washy feelings about someone today: you have to pick a side and proclaim either your loyalty or your opposition to what they are trying to do. Do not make a dramatic announcement to get your point across, just state your decision and carry on. There is no need to add drama to a situation that may already be a little tense. You can't try so hard to save someone's feelings anymore: it is getting you nowhere.
