20,000 subscribers! Wow! Of course, we wish that it could have happened under happier circumstances - we know many of you have joined us purely because of school closures over the past year. So to all you students who love or loathe watching our videos; to all you teachers working tirelessly to plan and deliver lessons (we know what you're going through!) - we should all be proud of how we've come through everything this past year. You might be tempted to accept it as 'normal', but in reality getting through every day is a victory. Thank you so much for subscribing and watching our videos. We hope that you have less reason to watch us soon; but we hope you will still find us useful in the future regardless! All the best!
