Being homeschooled, I feel like I must tell you that everything just said is not true. Many of my friends are homeschooled, many are not.
I have friends from many areas of life, and honestly find myself to be very busy with all the social activities I do. I learn alot more than any public schoolers, because I don't text people on my phone all day while falling asleep to a monotone teacher's voice. I got the presidential gold volunteer award 3 years in a row, and am an active part of my community. I have seen many of my friends go from public school to homeschool, but never the other way around. Also it helps keep families closer. My mom read me bedtime stories before tucking me in to bed until I was 15, and my brothers and I spent alot of days playing board games together or taking walks around the block and talking about our life goals.
However, it can be weird too, I agree. Sometimes when in public I didn't know what to say to people. I always got made fun of for hiding in my house all day by the big kids down the block. I was on an airplane once and I was scared so I brought my stuffed frog with hearts on it (a valentine's day present) and I got a lot of mean looks and glares. So people can be stupid about it but homeschooling is good. I fully support it so knock it off.
