You should post your experience, whether positive or negative. That's the entire main purpose of this board. It doesn't matter whether every single other experience has been positive or not. The sum of all the reviews is what can paint a general picture of the person you're seeing, and the more reviews there are the more reliable that information will be, and the more helpful to board members. It's not about painting sunshine and rainbows all the time, which does a disservice to everyone. That's not doing any of your fellow members any favours. It's about providing useful, actionable information, good or bad, that others can use. Having said that, there's no reason for you to go into all of the minute details if it makes you uncomfortable or if you feel it may be harmful or inconsistent with the SPs usual behaviour. Anyone can have a bad day, and a lack of chemistry can happen to anyone too. Use your judgment and post what others should know, and anything else can de done in DMs.
