What should I do if someone has their fly down?

If someone has their fly down, you should tactfully point it out to them and offer to help them fix it. You can say something along the lines of "Hey, your fly is down. Can I help you with it?" or "I noticed your fly is undone. Would you like assistance?" It could also be done in a more casual manner, such as saying "Your fly...do you need help?" depending on the situation. Being as casual and discrete as possible is always a good idea, but ultimately the best way to handle the situation depends on the atmosphere.
