Good grief! I hope your sons' unlucky streak will end before they start to drive.
You and me both. But I can always refuse to sign their permit/license (need parental permission) and force them to take the bus till age 18. I'm a mean mom like that. Unfortunately, they get their clumsiness naturally - It's been said that I trip over dust by my former roommate/bff.
It's a total catch 22 - we don't want them staring at screens 24/7 (which is what they'd prefer) but then when they play sports or just play outside with friends, they injure themselves. But at least they have good BMIs, LOL.
