Yes, I know, this may be an unpopular opinion, but I don't give a damn. This is my opinion on why I dislike nostalgia.
Personally, nostalgia is kind of stupid. You can be nostalgic all you want & think about the "good old days & better times" all you want, but in my opinion, nostalgia is annoying. Has anyone ever hear of the quote: "Let the past be the past" I don't like dwelling in the past. You know, there's a reason why the present is called present. Anyways, the past is stupid, the future will be depressing & we are all going to die alone. :)
