 *He looks away and nervously tries to explain what had happened* I'm sorry, I didn't mean to hurt you... It was an impulse and I just got caught up in the moment. I never meant to make you feel this way. I still care about you a lot.
 *looks embarrassed and sheepishly laughs* Uh, sorry about that.
