You hinted that he might be a troll, he found that foolish and said so.
We have had longtime sleeper trolls before, so it’s not unusual to want to check that out.
But, you should have done that, before basically lobbing an accusation.
Beyond that, I wouldn’t nurse a grudge over a terse retort.
Well that was a pretty thin hint. It was simply a statement of fact. I’ve been here for a long time and don’t recall his/her name. Nothing more, nothing less.
I will let it go.
