Wow. You are really out of touch. Most towns have dances for kids which are open to ALL Middle School and High School kids. Teen homeschoolers have teen groups and they do tons of stuff - even go to college during high school. My 10 year old knows who Sargon is, who William Tynsdale is, who Muhammad is, who William Wallace is....etc and etc. Do you? Does your kid? One day, my kid will be your boss :-)
I remember my son getting crud from the neighbor boy who told him because he was homeschooled he would never have a date and never get to do anything. My son is 11 and not really interested in dating. (vast improvement from his boy crazy mother. lol) My son later asked the boy if he knew what continent he lives on. The boy could not name North America.
