history: I was hoping to go on vacation this summer but could not get the time off. I'm grateful for the work hours_comma_ but bummed that I can't get time off. Sorry to hear that. Maybe you can talk with your boss about changing the schedule a bit. Well_comma_ I've worked without a break for the last 3 years_comma_ I just want to get away abit.
current: Wow, that is a long time! That shows how dedicated you are to your job, and that you deserve some time off!
next: Right! I'd like to go lay on a beach, or even just the next town over at this point.
