Little dark secrets, never to be told. The kind that haunts you at 3 in the morning.....
Have to say though, it's a rare occurance in my experience, the whole freshers week thing turns so many heads as people realise that they can exist outside the small parochial social group they've had for years in their home towns.
I was single when I started uni, so was able to have some small distance as I watched relationships break down in hours, days.... a few weeks at the outside. One couple knee jerked into an engagement two weeks into uni so insecure were they (it didn't help in the end).
Of course, it might work out.... I simply wouldn't bet the house against it.
