Agree with adding additional reasoning, regardless of the actual tone.
I’ve received some feedback along the lines of “LOL Wut?” on a comment in code, which I really didn’t know how to take or respond to (suffice to say its meaning was vague, and generally unhelpful).
Sometimes you catch people in low energy or bad moods. It doesn't excuse the behaviour but try not to take it personal.
My trick is to write the wtf in pending review then go and look later in the day if it's still valid. Often I just needed to eat something and I'll be over it.
