Growing kids

We now have 3 kids in big enough shoes to require laces.  (At the stores we buy shoes at, you can't find velcro tennis shoes past size 12.)  This year both E and R graduated to shoelaces.  We bring them home and E pulls hers out, puts them on and runs out to show them all nicely tied... WHAT?  So she unties them, and gives us a demonstration -

We are speechless...  :)
