Relationships, money, what the future holds and so on. Relationships can be much more stressful than either of those in most cases. But, on the other hand, a kid that was screwing around with his ipod while he tripped me and right after that i kicked him while i was on the floor and he dropped his ipod (itouch) and he claimed it was my fault. Well, that ipod was worth 200$ supposedly and that would take me like 6 months to make up from my weak allowance so i was stressed out for a while. Well, anyway he got a new ipod somehow and all is well. I think it's not only money, but also relations ships and what may happen tomorrow are also stress creators.
