I think I just met a guy with split personality. We always on the same train to go to work. One day, he sat beside me, we never talk but as soon as I got out from the train, he return my keys I dropped without realising. I never got chance to thank him. 2days later, I saw him and thank him. He acted as if he doesn't know anything. I thought he forgotten. Today, we were in the train again. He smiled and bfore i got out, he said to never forgot my keys again. Yea.. I do realised he wore different style clothes. Twins or no?
