Not What A Mom Wants To Hear

I'm working inside the house, the boys are outside swimming. I can hear them through the window (and I check on them all the time. The rule is, they can swim without me there as long as they're both in the pool. Neither one can ever swim by himself). I can hear them playing, negotiating their next move. I'm not paying too much attention until I hear my youngest say: "Fine. Fine. But if we die, it's your fault." Warms a mom's heart.
