Well, for me, I have to because of the program I use for school. I also use it to research many topics. I've been writing articles about animals (and some other things), and I can't learn everything from a book. I joined this site because I wanted to learn about ducks, chickens, and other poultry. I love researching and learning about things, especially when we can't go out and do things now with the Corona Virus.
My parents trust me not to get into anything I shouldn't.
And I've been lonely af. I don't really have any friends, we've moved every year until now, and being homeschooled I don't get to see people often.
On here I finally felt like I had someone to talk to, even if ya'll think I'm crazy.
