helping the repairman

Sadly enough, we got home last night to discover that our A/C in the house was not working. The repairman came this morning and Dennis was fascinated by the whole process. The indoor part of our central unit is located in a closet in Dennis' room, and he stood by watching Mr. Hollon work. He would come back to the den for a while and then run back to his room and say "Hey, Mr. Holly, what you doing? Need some help?". He brought me a flashlight from somewhere and I presumed it belonged to Mr. Hollon and told Dennis as much. He took the flashlight to him and said "here Mr. Hollon here is flashlight!". It wasn't his, as it turned out, so I confiscated it, but Dennis kept finding it and taking it back to shine into the closet to 'help'. He was so sweet!
