I feel a bit sad about this weekend. I have to work on a big project for work instead of visiting my family.
I'm sorry to hear that. Hopefully after this project you can get some time off to spend with your family.
Thanks, yeah it's important to find the time to spend with those you love. I just couldn't make it this time.
I'm sure your family will understand. And look at the bright side, you'll cherish your next visit even more.
