Writing challenge nine

Two hours later we were ready to leave the house, Kerry dressed in a vividly bright floral maternity smock for our outing. I grabbed the house keys from the bureau drawer before we set off, reminding Kerry we would need to disable the alarm system on our return by punching in the four digit code. Yo Yo was full of excitement at being in the great outdoors, his level of energy incompatible with Kerry's advanced state of pregnancy so I sensitively and to my mind decently offered to hold the lead as the puppy somewhat shakily at first ran in circles enjoying all the new scents and sounds. The pop of a car backfiring suddenly disturbed the peacefulness and I felt the tug of the lead as Yo Yo decided to make a break for freedom.
