Which tense should I use for actions which terminate exactly at the present time and the final point of the action is the present moment ? Can present perfect be used for this type of situation?
Let's imagine a boy who left his house to go to his school sometime before the present time and I am a teacher standing at the door of his school now. Can I say "He has come to school" or "He came to school" at the first time he be at the borderline of the school when his coming exactly terminates at the present time and the action includes now(the present time)?
I think using past tense is not appropriate here because the action includes the present moment and using past form requires the action to locate in some past section at the timeline.
