This launched Luke excitedly into an imaginative story involving him and a classmate Ethan fighting fires. In the midst of it, he said that the fire was 'a pavilion times hotter'. I asked if he meant a 'million or billion times'. Robin from the other room informed me that 'pavilion' was a number Luke created. Luke let me know, "it's more than infinity."
Then I thought, "why not?" If a pavilion is an open-air shelter or tent and the root is from Latin pāpiliō, pāpiliōn- for butterfly or tent, (i.e. no boundaries, limitless, transforming...) then why not? Sounds better than infinity times hotter.
