It's usually about 20 to 30 minutes of relative calm followed by 5 to 10 minutes of "venting". Then the cycle restarts. My daughter drops them off on Thursday morning and picks them up Friday evening. We're always glad to see them, but my wife and I high-five each other upon their departure. :)
“... other items have met their demise”
Well, the football, soccer ball, softball, basketball phase hasn’t started yet. Give it time! LOL. My oldest brother has 3 boys (two grown now). Over the years, he has replaced every window. Simple accidents, really. (not all at once either so the spacing helps your sanity). I get the whole, “I love when they get here and I love when they go home”.
