Actually he was nicer before the pandemic while we were in the office. He always came by to show me stuff when I called him.
I've noticed the behavior of several other colleagues (not everyone) changed while WFH. Many became more distant and hesitant to cooperate and lend a hand. Most wanted to lock themselves in a "don't bother me for anything, let me wrap my work faster, so I can sign out for the day early" kind of state.
