LOLOLOL when people don't recognize me

I met an old coworker at my old place of employment today and no one recognized me!! It was hilarious when they greeted my old coworker (who quit there are few months ago) and just smiled at me until I explained who I was. They looked at me in shock and would immediately hug me!! It was so funny to see their faces!!! I loved every second of it. It's funny to me because I feel like the same person inside, but I realize that it is such a shock to see me 147 pounds lighter in such a short time!! I guess I would be shocked too!
