I don't want to subscribe I don't want to like the video, I don't want to share it. It's because I cannot understand you. This section of the forum is for the English language. Your language was I think is Spanish? Maybe, create a video that is in English and share that to us. I mean, I can see what you're trying to do in the video but it leads to wrongdoing if the viewer and the lecturer does not have a good communication with each other.
