Unnecessary!

We were driving back from Whistler last weekend when a single-vehicle accident happened a few cars in front of us. Fortunately the driver was okay and no one else was involved in the accident, even though traffic was quite heavy that day. Anyway...earlier this week, Braden was recalling the whole incident and was asking me if I remembered what happened. Then he asked me, "Mom...why did that lady crash?" I said, "Well, I think she just lost control and hit the cement wall." There was a long pause and then Braden says, "That was unnecessary!"
