Balloons

Yesterday, both the boys wanted helium-filled balloons.
The younger one’s broke minutes after buying it. He took awhile to realise it, but when he did, didn’t seem unduly perturbed.
Back home, the older one uncharacteristically shared his balloon with the younger brother. He soon lost interest in it, but the younger one continued to play with it.
I watched in horror as the balloon floated up and hit the ceiling fan. Waited for hysterics, but got a cheerful “I broke my brother’s balloon” instead.
Was that his way of cheering himself up, or had that been his intention all along?
