Alice interrupts Bob's profound speech with a loud snore
Bob and Alice are having a conversation, and Bob is telling Alice some very profound things. Never have such powerful and meaningful words flowed from Bob's mouth. And just as Bob is about to get to the crux of his glorious monologue, Alice lets out a loud snore. Nice work, Bob, your profound words just put Alice to sleep. This trope is about a speaker who is so boring that nearby listeners are not able to remain awake, often to the speaker's chagrin. Commonly, the speaker is interrupted by a snore. Usually done for comedic effect. Sometimes the speaker will magnanimously tuck the listener in after realizing that the listener fell asleep. Related to Long Speech Tea Time, but this trope is about characters falling asleep on the speaker rather than ignoring them.
Would like some opinions on whether this trope should be about any time a speaker puts a listener to sleep, or only for cases where the speaker is interrupted somehow (not necessarily by a snore, though). I think the former may be too broad, and possibly subjective (is the speaker boring, or is the listener tired or disrespectful?).
