history: My car broke down recently, now my brother in law helps me get around and I can't thank him enough. I've been having car trouble lately_comma_ but my brother in law has been helping me get around. I'm so thankful towards him./
current: That's so nice of him to do. No one wants to help anyone out these days but I'm glad for you.
next: I wouldn't know where to turn if he hadn't offered to help. I hope I don't burden him for too long though.
