Student or Learner
-Where are you working?
I'm working in the USA. (even if I am not at work at that moment in time but are in the supermarket, or at a friend's house).
-I am studing English. (even if I am not doing anything about studying English, maybe maths...).
Are they OK, even if the events don't occur in that time?
Can we apply this for all the verbs also?
In general, I am sleeping here, but today I don't want to sleep here anynore.
Is that OK?
