Facts, now I’m zero for 5. So you are not only one who’s losing over the collegues/frens. 
Worst it that few of them came back to me in these days and wanted explanation again. 
I’m not that type who will try to explain something to them again, when they allready showed me ignorance, so unless it’s someone from my family or close friends, I’ll never giving them another advice or explanation 🤪
