snarky comments, imo, are the results of people assuming they are thinking out of the box. initially, it could have been done without malice, just pure i'll up you one better thinking.

as others have said, there's also that factor that the person is h-p-d/k-s-p/socially-challenged. (edit: i mistook add/adhd for what really is hpd)

in times like these, i'll advise that tending to your mental health is always a good practice.
