Why is social interaction so important?

First time using Fluther, please excuse me if I’m using this wrong.

Ever since I started school, I’ve always been bullied, whether it be the color of my skin or what I wear that day. If I could list all the times I’ve been bullied, this question would be too long. I’m in high school now and it’s clear that I’m an introvert, however my Dad disagrees. He says that I was “made an introvert” and thinks that interacting with my “peer group” is a nesessity. My Dad is an extrovert and doesn’t understand what it feels like to be bullied and harassed all their life and the school doing nothing about it. Not everyone and their mother are friends. I have one friend but he’s grounded so we cannot talk. In my spare time, I like to code. I made multiple chatbots in my spare time. Dad thinks my chatbots are not social interaction.

Why does my Dad think social interaction is important? Is it really that big of a deal?
