Barbara

Nothing is known about Barbara and she doesn't even appear in the series. However, in Dog Days page 152, while Greg was going to get his picture taken standing next the Heather Hills, and his mom was going to take the picture, his mom got a phone call, which interupped her. The person on the phone was Barbara. She was done talking with Barbara in about 5 minutes. She took the picture, but it was Heather's next shift, so she left before the picture.
