Only those who know you, recognize it. It is a disguise to protect you and mask your true reaction. It is frequently used when facing a loss; whether it is a job, a promotion, a loved one, your youthful appearance or even your hair.
Recently, I had a fake smile day. I found myself dreaming most of it and not getting much done. I am a "Doer" not a "Thinker", so checking off a list at the end of the day has always been important. This day, I allowed myself to dream. Dream of what could have been, should have been and what I still want to be. I allowed my dreams rather than my actions to be a better part of the day. It made me cherish existence a little more when I was able to snap back to reality.
I started my day with a fake smile and somewhere along the way. I felt the smile and allowed it to be real. I set this feeling free. It is a not a great day, but I challenge myself to make it a good day, because I realize that life is a gift and a dream can make it even better. If you can use the fake smile long enough, it may evolve into you actually feeling like smiling. And if you take some time to dream, you may find a reason to smile.
