Book Sale Today

Ricky : “So, today is the first day of our two day book sale. Our library board president parked his tractor in front of the library so we could get people’s attention and let them know we’re having a book sale.”
Me : “I think it’s working. It got those two guys to come over..”
Ricky : “To see the tractor! Not to come to the book sale!! Mom… I don’t think they’re readers.. I think they thought the sign said for sale. Should I ask them if they know how to read??”
Me : “Omg, no! Shhhhhh!!”
