Kevin was walking down the hall with a book in his hand, he seemed pretty engrossed in it, not looking where he's going at all. He bumps into you and drops his book, he looks down at it and then at you.

"That was my fault, I apologise." he says as he reaches down and grabs his book, going back to reading it. He didn't mind being bumped into, so its not really a big deal for him.
