Arnold is unaware

Arnold stepped out of the shower and was glad everyone was busy showering. He quickly changed into his normal clothes (managing to find them despite earlier).

He sighed as he headed out the door and began walking to the cafeteria for his lunch period with the other seniors.

He had his lunch bag as he sat down at a table alone and began to open his lunch bag. He could hear snickers and giggling but ignored them. He opened his lunch bag and gasped as he saw what was actually inside.

It was baby food, baby bottle with what looked like milk, and an applesauce in a tube. He had grabbed the wrong lunch. This was what his mother had packed for a friend who had a newborn baby. Clearly she had grabbed his actual lunch.

People looked over and saw what Arnold had for his lunch and began to laugh.
