WHAT THE HECK

Why is this puppy sad?



Because I have received no inputs for what strikes me as a really simple challenge. 

Help make the puppy happy--take the challenge.  Here it is again:

During World War Two, the border crossings between Germany and Switzerland were carefully guarded. One such crossing was a bridge across a stream; it was a long bridge and took about 5 minutes to cross. The guard on the German side of the border stood at the end of the bridge and had orders to shoot anyone trying to leave Germany without a pass. If he saw anyone approaching from the Swiss side without a pass he would warn them and direct them back to the Swiss side. He (the German guard) made his rounds in a predictable way such that he checked the bridge every three minutes. He was meticulous and a deadly shot and yet an escaping prisoner of war successfully crossed the bridge fleeing Germany to the Swiss side. How did she avoid getting shot by the German sentry?

Because of the sad response so far, the this challenge has been extended and will now close out at 0730 Friday, 19 October.
