"Next Friday I am going to the mall."
It's Monday right now. Does "next Friday" refer to the Friday in THIS week, or NEXT week?
Or, consider this sentence:
"Last summer I went kayaking."
It's October right now. Does "last summer" refer to the summer in THIS year, or LAST year?
This is an ongoing and severely frustrating debate with my boyfriend and I. In my mind, NEXT Friday is NEXT WEEK'S Friday and LAST SUMMER is LAST YEAR'S summer. It just... makes sense. D:
