When we're in a happy mood -- whether because we nabbed a promotion or landed a date with someone we've had our eye on -- we don't hesitate to express our emotions. We might smile, laugh, cheer, post a buoyant message on social media, or treat your friends to celebratory drinks. But things play out quite differently when we're going through a rough patch in our lives. We might instead hide our emotions -- sadness, anger, jealousy -- because we don't want to worry others or compel them to probe. As a result, we might turn down invitations to attend parties, call it a night unusually early, and shelve the kinds of things we look forward to when we're in better spirits, like hobbies.  There's nothing wrong with playing your cards close to your chest.
