Correct, they socialize in workshops, in extracurricular activities, in the park, with neighbors and family, just because it is not inside a classroom in a formal school does not mean that they will be asocial. Regarding making friends online, I am not at that stage yet because my daughter is young and I do not give her that access at the moment, but she will arrive that day and will also socialize through that medium. Actually in another time, I learned to read with a book and I taught my daughter to read with YouTube, she didn't pay attention when I tried to do it with a book similar to the one my mother uses with me, so I thought "new era, new methods" and it worked excellent.
