Being someone who keeps their word can have value, but sometimes it doesn't. If someone kidnaps you and then forces you to promise to give them all your money when they release you, it's bad. If they knew you wouldn't keep your word, they wouldn't have kidnapped you. That's why contracts made under duress aren't binding. I don't think duress is the only reason to break a promise. Another one is that you were stupid. You don't want to make promises you'll later regret, so if someone doesn't accept your promise because they predict you'll come to regret it, that's good.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
