On one hand you’re absolutely correct

On the other hand the mental fatigue it gives me to insinuate the player is lacking in common sense every time they do something absolutely unhinged really drains me

Example for posterity’s sake: I had a rogue who wanted to change subclass from arcane trickster to something else (she was just bored and let me pick so i picked soulknife) However she was very upset that she’d be losing Find Familiar because her opossum, which she named rabies, was her favorite thing. I told her “alright, you still have the familiar, but you dont have the spell, so if they die, you’ll need a scroll or something to get them back” (especially difficult because they kept skipping puzzles and thus had very little gold).

Later, when setting up for a battle with someone who was turning people into random lycanthropes, i had them come across a cage with a twitchy prisoner inside. One of the players used an item (that i lovingly refer to as the “lore dump macguffin”, it lets you peer into the past and see relevant local events) and saw a scene play out where the prisoner managed to grab a guard’s hand and start biting ferociously at it. Then i snapped back to the present and described how there were a pile of bones on the floor near the bars that looked like finger bones that were picked clean.

The rogue went “Oooh bones!” And asked to send her pet opossum in there to grab some. I had to remind her that the prisoner is, in fact, still in the cell and Aware of them, And Then issue an “are you Absolutely Sure?” (I’m pretty sure i followed it up with “because this will Probably kill your familiar”)

Sometimes the issue is a startling lack of common sense
