The lyf so short

An acquaintance of the M-I-L has harvested mushrooms (honey fungus to be precise). In fact, she has harvested so many mushrooms that she's been eating them for several days, is now thoroughly tired of them, and has given the remaining two baskets (?!?!?!) to the M-I-L, who has given me one. We had mushrooms for dinner yesterday and for lunch today and I'm already tired of them. (Mostly because they're a PITA to prepare. The taste is alright.) And I can't help wondering why the HECK someone would harvest more mushrooms than she can (evidently) use up in a week? Like, doesn't she realise that you can... leave the rest and come back later? Or even not come back, and let others not yet tired of the things do the picking? Why do you cut so many mushrooms that you no longer enjoy eating them and still have two whole-ass bakets to give away (or throw out)? I guess it's a generational thing but it just makes no sense to me.

Also, my German mushroom guidebooks unanimously tell me that honey fungus shouln't be dried because you NEED to boil them before eating, while English mushroom sites state that drying is a good way of preserving them. Whom do I believe?
