Most nights I fall asleep to the ambience of a severe windy snowstorm... I find it comforting whilst I'm wrapped-up under my covers. It makes me feel like I'm in a tent outside.
When I'm off work - nothing, the room is as quiet as a mouse
When I'm mornings - the joyous sounds of boy racers, constantly driving up and down the street.
When I'm nights - the neighbours cutting the grass or doing DIY stuff.
