Caught Red Handed

From the title many of you have probably already guested this is a story about Luke. Today while Rachel was taking her swimming lesson Chris went and picked Luke up from school. When they got to the pool Luke had to go to the bathroom. Chris asked if he needed any help, but Luke said he did not. After Luke had been gone for about 5 minutes Chris went to look for him. Chris met him crying in the hall coming toward him. Chris looked down and Luke's hands were blood red. Chris asked if he cut himself, but Luke said no. Chris had him to show him where he had been. Luke took him to the bathroom. There was a trash can with a sign "Under Maintenance" in the middle of the door way. Apparently, the restroom was being painted and Luke found it. Chris cleaned his hands as best he could, but they are still red.

Isn't there a saying about red palms?

Luke's skin is usually as pastie white as mine.
