decisions made while speaking: 1) i’m tired, i’ll go to bed. 2) i’m going to sit in the garden this afternoon. oh no, it’s raining. i’ll stay in the house, then. 3) i have decided. i am going to make an omelette for dinner. Ah, there aren’t any eggs, i’ll make a cheese sandwich, then. 4) I decided. i am going to the mall. Oh for god’s sake! there are no trains today! i’ll stay at home, then.
