Quite a few years ago a previous GF moved in (sort of, she had her own room in a shared house with her friends) and when i was away for the weekend she decided to rearrange my living room as she always threatened to change it, according to her it wasn’t friendly or nice for folk (ie – her friends) to sit in. She removed my stacking Hi-Fi and B&W 603 floor standers with the cabling, she removed the acoustic tiles and bass traps i had on the walls and ceiling – she bought a gopping throw for my Mies van der rohe Barcelona sofa and moved my big comfy square Habitat listening chair to the corner of the room and she bought a 2nd hand massive crt tv for the corner of the room and she filled every surface with pictures and utterly pointless crap.
I went batshit crazy when i got home, everything was moved back into place the following day, and she ended up living back in her flatshare with the CRT TV within a week.
Prob why i’m still single but to be honest i much prefer it, i make as much noise whenever i like, i’ve realised i’m far too arsid to live with anyone.
