So I have been studying many examples about this. I want to make sure that I am right in assuming the following and have a question in the end. So today is Thursday.
In the last week, I have been on four dates.
This means from last Thursday until today, I have gone on four dates. These four dates could have happened on one single day of these days between last Thursday and today. Or maybe two dates happened on one day and another two on another day between last Thursday and today. Or another time occurences.
Last week, I went on four dates.
This means last Thursday I went on four dates. Meaning on that day, I went on four dates OR last Thursday, I had been on four dates, meaning that I could have gone on these dates any day before last Thursday?
