Poor kid-so lonely due to mom's fears?

I am reading about a little girl on another site. She is home schooled, but her parents do not allow her to participate in any home school groups, Girl Scouts, church groups, etc. The poor child is isolated with no friends. It seems the mom has some fear/paranoia about any outside activity for the child. Perhaps the mom had a bad experince in the past. So, the child has no friends or activities.
