James is sure the glitter will stick around long enough for Lila to get a proper kick out of the joke. He'll be trying to scrub it off for days with the amount there is, and he's sure Lily will find it covering their furniture soon enough. "I could do a repeat performance, if you like," he offers, smiling a little. "If only there were more glitter."

She's here to prank him rather than say happy birthday, that much is clear, but James is in a good enough mood that he doesn't even really mind. It's a harmless joke and in truth he's gotten a laugh out of it as well. "It's the kind of prank we might have pulled in first year," he tells her with a laugh. "In fact, I think we did. I seem to remember Sirius being determined to cover Snape in glitter head to toe, cheer him up a bit."

It hadn't worked, obviously. Snape was a miserable sod no matter what, but James at least had gotten a good laugh out of it. "But it was a good first effort." He pauses, considering. "I'd humbly request that you don't revenge kill me on my birthday. Bad form."
