I feel like "I went to school at 7 am" means I started waking out of my house at 7 am and then was on my way to school. Maybe, I would arrive at school in 15 minutes at 7:15 am.
However, chatgpt says "I went to school at 7 am" might mean both "started going" or "arrived" depending on the situation or context.
But, I feel like "I went to school at 7 am" tends to say I started going then I arrived, but I am not sure.
Does "I went to school at 7 am" mean I started going to school at 7 am or I arrived school at 7 am?
