Your little ones need you far more than we do.
The most complex ones need to be performed only once in a lifetime.
"Anyone 16 or older will know what to do, but the young ones need to be told to follow traffic laws."
But loved ones often want and need to hear what the elderly person has to say.
Children 9 years old and older can assemble it; younger ones may need help.
But the ones who escape will need a leader, too.
She'd have to make a study of their performance and figure out which ones would need additional drilling as time allowed.
So the categories either have to expand or new ones need to be created.
While you're waiting, look around and see which other ones need your attention.
So probably won't need to worry about the acceleration ones.
