Why not the preseny continuous,too ?
It should be accepted, please report it if it is not.
The present continuous was not accepted!!?
Kids vs children, why the first isn't acceptable?
"Kids" is informal English. Where do you draw the line? "rugrats"? "brats"?
I don't and I wouldn't. It's just an expression of curiosity that in some cases (language courses) "kids" is perfectly acceptable - and for some reason it's not here. and of course it's shorter :)
