Is it arreter (not s'arreter) because "ce que je faisais" is the object and s'arreter as a reflexive can't have an object??
And unlike 'the rest of the day' (journee), I felt better 'in the evening' is not obviously 'duration' so why soiree not soir, especially when this morning is matin?
Why faire (bien) DE venir when faire doesn't have to take a preposition and A is the normal connector in those circumstances?
Is there any rule at all to determine relaxer vs se relaxer vs detendre vs se detendre?
And on and on it goes ...
