Well there are questions and questions, and also many ways of and times of asking them.

For example, and oldie but goodie is: http://www.catb.org/~esr/faqs/smart-questions.html

That might be overkill for internal review situations, but it is worth reading and bearing in mind.

Context is all. Sometimes it is the problem of the person you asked. Sometimes it is just the wrong time. Sometimes they are under pressure or just feeling a bit grumpy and snap at you. Sometimes there really is a "stoopid question"! Sometimes you need to try asking the rubber duck first (https://en.wikipedia.org/wiki/Rubber_duck_debugging)!

Keep your chin up and don't take it personally!
