You can find the rules for Ringer all over the internet, but I think they're especially easy to follow at Scouter Mom. Most people play it outside for obvious reasons. Big Sis had her turn at a sick day yesterday, so they played inside after Little Sis came home from preschool.
Please think good thoughts for our Siamese kitty, Katie. She's at the vet this morning. She hasn't been feeling well.
