Yeah, sometimes people will just tear down others out of jealousy. I saw a lot of that when I was in the military. It was depressingly common to have one group leave for the day, and someone who still had work to do would call out, “Must be nice”. I always hated that. I was assigned to a submarine(which was really awful since the sub force was all male at the time and I was a closeted trans woman), everyone had it lousy. I would always think to myself, “Is it really that hard to be happy for someone, instead of being bitter that you have to stay longer”. Now, granted, there were some people who had demonstrably worse times due to workload. But that doesn’t give you carte blanche to be a drag on everyone else.
