<s>[INST] Why wouldn't you consider poignancy to be the opposite of nostalgia? [/INST] Although both nostalgia and poignancy may evoke the general feeling of reminiscence, poignancy can also describe something in the present that causes one to feel regretful or sad. Nostalgia, on the other hand, generally refers to that which evokes feelings of longing or sentimentality in reference to past events—although the originator of that nostalgic feeling may currently be present, its subject is in the past. As such, nostalgia and poignancy may not be considered antonyms in a general sense.

For example, the night sky may be poignant for someone who imagines the smallness of their place in the world upon looking up at it, however they wouldn't necessarily feel nostalgic unless they had some particular experience under the night sky worth reminiscing over.</s>
