I'm kind of embarrassed about this, but here goes my first attempt at voice-posting. I hope this doesn't screw up.
Also, just as a point of interest, after you've watched the video, can you please leave a comment about what accent do you think I have? Because I've asked a lot of people this, and every one of them has given me a different answer, and I can't hear my own accent.
So yeah, all my explanations are in the video, so, I'll stop waffling.
