First of, where do you live? I mean, cold winter's night. I've lived through those. Then again, there's a 30 minute walk from anything down town to my place, so I can always pull myself together and walk. We also have open sub-way stations and train stations (we have night trains, for Christ's sake), so it's possible to get some shelter. Why did the party end that early, anyway? When the tram and bus stops for the night 'round here, that's just before the real party begins. Later, it's the after party. Then the tram and bus is usually back up, for it is morning.
Anyway, besides that, I don't understand why you find it amusing you broke up, unless she was a bitch, that is.
