This might be a better question for, say, another evening, BUT... if your house is going up/down, one way or another, what are the three non-essential items you're grabbing? Not talking fire safes, passports or insurance docs.
Mine are... 1 x Toby's ashes (potentially ironic) 1 x Mofusand plushie 1 x LV handbag (one is a particularly loved piece)
