Some of us old cantankerous farts forget that not everyone knows what we know. So to us some things seem too obvious to need to be asked. Sometimes our delivery is a bit abrasive as well.
Perhaps we can all try to be a bit more like 2000 grit than 80 grit and also at the same time we can all toughen up our skins just a bit.
Maybe we could treat others with respect? Crazy idea I know. Or just answer question or scroll past. You get what you give! Cranky old timers should know the golden rule. Maybe they forgot?
