jerry went on a ten-block marathon.it was the first real exercise he had had in days and it felt good to work up a sweat.if anyone had been following him , they would have had to be in pretty good shape to keep up.jerry had been in training for this little cat and mouse game whether he realized it at the time or not.after clocking about two miles in less than twenty minutes , he ended up at the service entrance of sheilas complex.security was nowhere to be found and he casually made his way back up to sheilas apartment.when she opened the door he said , the security in this building is going downhill fast.i just came up through the service entrance without any problem , and that furniture delivery thing today was a fiasco .
