@Jules I started out as a boot camper, and they emphasized the importance of asking questions and being open about being confused/not understanding things.
Working professionally in the field, I've never stopped being open about that stuff and try to encourage others to do the same. Communication is key and everyone benefits from knowledge that might not have been shared if the question was never asked.
Anyone who snarks in reply is a horse's ass! And it comes off as insecure.
