Rainy days

How do my kids know that it is time to play in couch pillows again immediately after I straightened them? Must be the same way they know the table cloth is clean so it is time to make a big spill during dinner? Could it be connected to the time to eat crackers for snack after I swept the kitchen floor? I love the current weather change of clouds and rain (since school has started and it's still hot), but my kids are going stir crazy being shut up inside all the time. Makaila has had her volume turned on loud and can't hardly sit in her chair for more than 30 seconds. Sure hope we get a chance to go outside and play this weekend!
