I always find it funny when you see a WG for the second or third time and she forgets what she has told you om previous visits, so you get a different story each time...
recently the same girl has told me:
She is at 2 different Universities
She is studying for 3 different subjects
She is 22 (1st visit), 24 (2nd visit), 23 (3rd visit)
She lives in 2 different cities
