In one of my nursing tutorials, there was this girl who got turned away at the door because she arrived late (our teacher is strict on the 10 minute policy). I had this random sense of familiarity, even though I haven't even seen her before. The class was later divided into 5 groups of 5 for our team assignments but I didn't mind which group I ended up in. Our group was missing one person- so the teacher just put her into our group. I guess the feeling meant that she was supposed to be a part of our team. >.<"
(I wouldn't call it a massive coincedence, but our team was lucky to be able to pick our topic first while the others fought it out amongst themselves!)
