That's good of you to be concerned for others, Partless. I tend to think it's no different than children raised in what appears to be a good family, the ones that no one has any idea what's happening behind closed doors. So, having neighbors isn't always a guarantee. I saw an absolutely dreadful, verbally abusive one who shared a practice with two others. Fortunately, it happened within the second session so I was able to see the writing on the wall and get out before it was too late.

I do think that it's a good idea to be cautious no matter what the setting.
