Bonfire night

A conversation yesterday:

Dude:  Dad, can you get some sparklers on your way home from work?
Me:     Yes, of course I will

(later)

Dude: Yay, sparklers.

Me:    Okay, hold still, I'm just going to light it.
Dude: Light it? What're you doing, are you setting fire to it? Dad, what're you doing?

(by the last sparkler in the pack, he was enjoying himself...)
