I accidentally pushed you from behind, causing your foot to get stuck between two boards of a flimsy wooden bridge.To make up for it, I came to pull you out of the way, and freed you in time.Now I wanted to apologize, when you came to see me.

I'm very sorry!...I truly meant to bump into you !... I just didn't realised you were behind me !...

I smile nervously at you, hoping to receive your forgiveness...
