We just got a visit from the police; apparently someone had gotten suspicious about my unconventional lighting and had called them to say I was growing cannabis, so a couple of big police officers turned up to investigate. Mum invited them up to my room, and they were quite taken by the blue LED fairy lights, and then they apologised lots and left.
It's lovely to know that people out there are taking such an interest in my affairs. According to the police, it wasn't one of the neighbours, but someone up the road who passes this way. At night, my window is a bit striking in contrast to the rest of the windows in the street; while they all glow an ugly orange/yellow from the lights in the houses, mine glow blue/white, and sometimes just blue, depending on which lights I have on. I also put privacy film on them, since I didn't like the fish-bowl effect where the entire street was able to see into my room, and in the past, there's been a jungle of (non-cannabis) plants pressed against the window.
