Yes, this is where I feel a downvote is not appropriate.
I can see why one has the urge to downvote this though. It has to do with “ruining the positive atmosphere”. Instead of offering alternative view, heck, even just a simple encouragement, some people just default to knee jerk reaction of disapproval.
It feels like a form of discrimination against unhappiness. It reminds me of the book 'Brave New World' - In the book, unhappy people are looked down upon and they see sadness as an illness which needs to be medicated with 'Soma'.
