to omit.

I have been puzzling over the list of vows in Kol Nidrei.  I finally have 
some grasp of their halachic definitions, but I'm having trouble thinking of 
modern day situations when each type of vow is made.  We have Neders, 
Assurs, Cherems, Konams, Kinuyei, Kinusei, and Shevuot.  Neder is easiest; 
I'm always trying to avoid them.  But can anyone help me come up with 
examples of vows in the other categories that someone might actually make 
nowadays?
