history: I wish I could have visited my family this weekend. But I have a big project to work on. I feel a bit sad about this weekend. I have to work on a big project for work instead of visiting my family.
current: I'm sorry to hear that. Hopefully after this project you can get some time off to spend with your family.
next: Thanks, yeah it's important to find the time to spend with those you love. I just couldn't make it this time.
