I would explain why my theory seems more valid, once. And then let it be. It makes no difference to me what they think if they are anyone.
Thank you for your advise, I will think about that.
Correct them and explain why and how.
I wouldn't react at all because that's their opinion.....
If they had a valid suggestion, I would take it into consideration and likely try their way, but if I felt they were wrong, I would either tell them so, or just ignore them and do it my way.
I'm gonna fṳcking correct that person.
i would say no , my idea is better but thanks anyway
Debate about it or ignore them if I was 100% sure I knew the answer.
I would not here it
smile and leave
