"One time is all you need to convince me you're capable of starting something on fire a second time," The Doctor noted as he pointed at her, then turned back towards the tree at hand while she tried to help him, "Oh, no no, you do your thing I have definitely got this. This is the 'man' thing; which, by the way is sexist, and also, I'm a Fae, we have different parameters."
He nodded with a huff then stuffed the tree into the stand, took his step back, and marveled at his work. Of course, The Doctor forgot about the screws to hold the tree in place, and it began to tip over and before he could react it ended up slamming into the window, not breaking it, but causing the curtain to fall and tumble over the tree.
"NO NO NO! Oooh... I liked those curtains... now they're all sappy."
