Ultimately, I don’t believe that there is a “one size fits all” answer to this question — as it must take into account several factors:
1. The temperament of the bochur.
2. The background of the bochur and his previous experiences.
3. What type of school he is going to (going to a public school while living at home is much different than dorming in a co-ed environment).
and probably a few other factors I neglected to mention. For some people in some circumstances, it would be absolutely right, while in other cases it could be incredibly wrong. Each case needs to be weighed individually.
