What is this and why was I invited to read it?

Hey everyone. Jo here. I just moved to England. I'll be here for a while. I've never been abroad, never lived farther than an hour from home for more than 2 months, so I think this will be quite the experience for me. I won't see you all every day, I don't have a phone and I can't drive to see you, and I'll miss you quite a lot. So, this might be a good way to communicate with everyone who wants to see what I'm up to. And it will help me feel like I am part of your lives and that you are part of mine. Josh, being the cool blogger that he is, suggested that I make one, so here you go. I regret that mine won't have sing-a-long musical numbers, but I'll do what I can.
