Us: Come on, Roxy, try this cat tunnel we bought. It will be fun!
Cat tunnel: *rustle rustle*
*6 months pass*
Me: Man, look at this thing. It's been gathering dust in the garage. I should probably just give it away... well, maybe we'll let Roxy give it a quick sniff for old times' sake.
*40 seconds later*
Oh, yeah, also, it's my birthday. For those who take an interest in such things.
