Yeah, I have. To be honest, I don't think I've really done very much to impact anyone's life, so it's not hard to imagine ^^
I think my parents would have more cats, and my friends... well, they would just be 100% wholesome instead of 95% wholesome and 5% sarcastic with me in it, haha.
My teachers would go along as they always have. I'm your traditional quiet nerd, pretty under the radar from my teachers' perspectives.
Hm... Bean (one of my cats) probably wouldn't be at our house anymore, because I found her when she got lost.
A couple of online friends would be lonely, and others wouldn't.
Other than that, life'd go on.
