I used the dust pan to scoop everything up and dumped it all into a toy box. I sprayed my hardwood floor cleaner, wiped it up with a rag and was done quickly. I did a few other things in his room to use up the full 15 minutes.
It's a beautiful day, so I've got to head outside with the family. Spring is on the way!
