There are going to be a lot of enthusiastic people around you today, which is usually fun. But the trouble is that what they are all excited about is really snoozeville for you. You're simply not feeling it the way they are. Rather than fake your feelings and try to hop on the happy bandwagon, just get your distance from the crowd. Go off on your own. If you stick around with that sour attitude, you could rain on their parade, which is no fun for anyone.
