Put two young children in a room with one toy and see what happens.
Their response can probably best summed up by a recent comic strip of the Baby Blues
For those of you who haven’t seen the comic strip
It is about a everyday family.
Two young children,
Hammy and Zoe are the main stars of the strip.
In this particular comic Hammy goes to mum and asks, “can I have a snack?”.
Mum responds by saying “sure, what would you like.”
Hammy’s response, “Anything that we only have one of.”
Mum’s response, “do you always have to do things to irate your sister?”
Hammy say, “No, only when there is nothing to watch on tv!”
