I would like to know how to express "I was supposed" in japanese
For example, in the sentences :
- Did you meet John yesterday ? - I was supposed to but he cancelled
- I am supposed to do my homework but I really don't want to.
Is there a generic way to translate that idea ? or is it case by case ? I am thinking maybe using ようになる but i am not really confident. somthing like :
or using べき maybe
Am I on the right direction ?
