This is a bit of a tricky one really - girls moods and attitudes May change from day to day, or even punter to punter. I know one lass who I get on with like a house on fire, we just seem to bounce off each other (literally ) but someone else, who's opinion I trust and respect, saw her and didn't feel the same way.
Horses for courses I guess.
Indeed. Prossies aren't "lovely" except when using polite flattery (or post-orgasmic haze and pink spectacles). They are prostitutes, workers doing a job, and either doing it well or badly or somewhere in-between.
I might
imagine, "She seemed like a nice girl" ... but I don't know her. I only know how she performed her job for me, on that occasion.
'GFE' is a disconnect with reality. You might as well say it's a lovely day cos you've just smoked a joint, had a Valium, or downed half a bottle of whisky.
