If you take a kid to the store,
he's probably going to need one of those little green carts to push by himself.
If he has one of those little carts,
he's probably going to want to put things in it,
and you'll have to follow him around putting everything back.
If you put everything back,
he's going to turn around and try to pick it up again,
this will make him drive a little crazy and he might bump into someone or knock over a display.
So, you'll have to pick him up and buckle him into your cart.
He won't like that very much and will probably start to cry--LOUDLY.
You'll try to distract him with a snack so you can finish your shopping.
He'll stop crying,
but he'll leave a trail of Cheerios that you'll have to pick up and stuff into your pocket.
Once he's finished the cheerios,
he'll start whining again,
so you'll hand him a yogurt to hold and, chances are,
if you give him a yogurt to hold,
he's going to want a little green cart to put it in.
