I hope so, its really stupid, you can't fail at picking a flower, oh geez my fingers slipped..
I guess people that say things like this live in a city and have never, ever gone mushroom, berry nor nut gathering.
It is perfectly possible and highly likely to fail at produce gathering.
Maybe it has a great big worm inside, maybe its too rotten or unripe or mouldy.
Especially for mushrooms, which need to be just right in their development, it is highly likely youll find mostly examples that arent any help at all.
Same with flowers.
Nature isnt a showroom.
Not everything grows perfectly formed, you know, and it is quite possible to hunt for, say, seeds, and fail quite a lot of the time.
