My happiest times are at Happy Hour - I'm happy to not be at work, happy to be with friends, happy to consume cheap drinks. There is breif disappointment when the clock hits 6 or 7 (depending on the establishment), but I just stick around and wait for Reverse Happy Hour (who ever came up with that is brilliant) and my happiness is restored.  For real ... what is there to not like about happy hour (another question in itself).
