Such a tease

It was a Monday Afternoon and the pack was having their usual meeting. The only problem was that Stiles, Scott, and Isaac, were late once again. Usually nobody minded because the three usually brought dinner, but this time, the three boys were 20 minutes late and the meeting had already started. Finally the pack heard the doors slam and an enraged Stiles say "STOP CALLING ME THAT, IM SORRY THAT I CARE!" They heard him start to stomp up the stairs while Isaac and Scott laughed their heads off. Stiles was almost to the door when Scott and Isaac raced up the stairs and made it through door and they dropped the bag of food from the down town diner, on the table. "DEREK! Tell them to stop calling me a name!" Stiles shouted walking in. The boys collapsed in laughter again and Derek asked what they were calling him. "They, they, keep calling me, pack mom" stiles said, everybody laughed and Stiles raced out, with a hurt puppy expression.
