My parents are nothing but the best...loving, caring, and spoiled me to death. I honestly have no right to complain. Yet I know that had the people around me not pushed me to break out of my shell and point out the fact that I didn't fit in, I would not be struggling with myself as a 25 year old. It's not their fault, nor do I mean to blame them. They were just uninformed, concerned parents.
I just wanted to take a moment to urge all parents out there with introverted children to accept them as they are. No, it's not healthy for kids to stay holed up all the time...but if your child seems to need a break from socializing, give it to them. They're not deficient and they're not in need of help. They are no less happy than any other child.
All an introverted child requires is help to cultivate their strengths and give them the confidence they need, and most importantly, deserve.
