You don't have to. I unterstood very well and, yes, I made a mistake. This happens. But guess what, it is quite natural since you can't harvest nearly any herbs when they haven't ripened yet. You have played this game probably a thousand times more than me and you should have known this. By the information given, I would likely do the same mistake again.
Thus, I have learned two things from you: First, I can harvest the leaves of bear pipe in game while it hasn't ripened yet. Second, people here, especially you, are quite impolite and if they are in a bad mood, they are insulting each other just for fun, because it isn't just enough to be right, trying to humilate others while having the advantage is fun.
Unlike me, you didn't learn anything. Now, the puzzle is solved. There isn't to anything say else, except for one thing maybe. You could save a lot of time if you were letting people doing their mistakes and not trying to educate them. People might actually think that you are a nice person then. So it was the best if you wouldn't say anything now. I'm done.
