They fight over the same book – even though there are dozens to choose from

And snatch food of each other’s plates

And give each other sly kicks under the table

And run off with other’s toys

And refuse to share their rice crackers

And play tug-of-war with the iPad 

And stand toe-to-toe, screaming ‘AAAAAARRRRRGGGH!’ in each other’s faces

And then they do this…
