the other day and it seems that they will send another teacher up there in their next trip.
Not only emotion and mood can change the cycle, I think that the food we have also plays role here. When I was at the university, I had a good friend and we did almost everything together everyday. We ate the same kind of food (well, not much choices anyway), we exercised together and we studies together. So our cycles are almost identical (the error is no more than a day). The girls in the same room used to laugh about it a lot.
