history: I have a friend who was constantly calling me last night attempting to get me to do his project for him. I really wasn't able to help him at all because I don't know anything about the topic.
current: I had a friend who was really driving me crazy last night. He was constantly calling me trying to get me to help with a project that he's working on. Unfortunatley I really don't know anything about his project so anything I could do was very limitied.
next: He should be understanding of that and not keep on. That's just frustrating for everyone involved
