Snap: All good things come to the bin

A new toy, I like it, to the bin; Mum's T-shirt, I like it, to the bin; my socks, I like them, also to the bin.
Whenever Kai finds anything he likes, he throws them to the bin. To avoid the trouble of constantly washing Kai's favorites, I close the kitchen door when I cook or put a clean, empty bin for him to play.
Kai must be copying Mum when he bins things, but he needs to realise, bad things to bin, good things to keep. Hope it doesn't take him long to get that.
