Sorry about that. I was an English major for a while.
Witnessing is essentially telling someone about Jesus. That's about as simple as I can make it. You're not necessarily observing the event of someone converting to Jesus, however, you are witnessing the even of them making a decision. Because at that moment, that person is either deciding to be for, or against Jesus. So either way, a decision is being made, and you are observing that event.
