Better solution to clingfilm as in works better, or more environmentally friendly?
My American friends introduced me to the revelation which is Glad Wrap - I have no idea why we don't have it here, it's like cling film but reusable, stretchy, doesn't stick to itself, actually fucking works 
If you want a more environmentally friendly option beeswax wraps are supposed to be good, but I have no idea if they actually are.
Short hair is brilliant. So much less time dealing with it.
I am not sure teleporting is really a little thing, but if we are allowed things like that, I always wanted Bernard's Watch so that I could pause time and just carry on having a lie in until whatever time I wanted to get up. Or allow me to walk to a bus/train stop at my leisure rather than huffing and puffing to get there in time.
I wish that you could make a force field around you so you didn't have to feel wind on a cold day. So annoying, and another hazard of having long hair as it flies everywhere, and gets stuck in your lip balm.
I wish I had glasses that didn't mist up when I wear a scarf over my nose. Maybe I need to fashion a device with some straws to redirect my breath out of the bottom of the scarf instead. Actually, anti-mist, anti-fingerprint and anti-dust glasses would be awesome please.
I also need an instant temperature regulator. Being too hot when you have wrapped up for the outside and then step into a heated bus or shop is awful. And the first moment when you get out of bed on a Winter morning is horrible as well.
