Thank God! Luck was on my side and saved me from banging my head.
At that very moment, I really thought I gonna banged my head on the floor. I even tasted blood in my mouth during the fall. No idea why, maybe it’s something like where you feel sour by only looking at a lemon.
The moral of the story: Stand properly while waiting for someone. Don’t simply sit on a metal bar as you might fall and die. :/
And wearing a dress is not a good thing. =.=
