The part that shows up at the end of 0:16, throughout 0:17 and ends at the beginning of 0:18?
Yes, that one exactly. The 18-second mark shows it quite clearly.
0:17 would have made more sense then.
It would have certainly helped prevent your blunder. Then again, so would you exercising the bare minimum of competence.
Like I said, anyone who doesn't want to learn can simply not watch.
Certainly. Similarly, if you don't want to hear dissent, you can simply not read the responses to your threads.
