Our very nice Greek neighbors (no sarcasm, I truly mean that) are definitely going to be told off for this one. Not by me, because they're not waking up my infant, but definitely by the Americans underneath.
I should point out (because I know someone's going to be like "10:45, what are you, a granny?!") that this is the beginning of the party. People just started arriving a half hour ago. Winter quiet hours began at 10.
