Socialization in Buddhism

I was just thinking of why it is that monks and serious practitioners avoid socialization. It has been stated that Buddhism is not about become more social but about become more reclusive.  At least for theravada Buddhism.  I think it has to do with ones inability to mindfully help others if they have not developed that mindfullness themselves.  It is difficult to develop any sense of deep mindfullness when you are busy helping and worrying about those you are helping.  This agitates the mind and makes it difficult to be mindful of what you're doing, unless you have previously developed some degree of mindfullness.  Therefore, before you can be very helpful to others you must first help yourself.
