I thought my best friend was going to be able to visit me this summer. But it turns out he can't take the time off from work right now. I'm a bit bummed, as I haven't seen him in a long time.
Would you be able to go meet him instead?
No, unfortunately I can't make the drive right now. Maybe next year. 
That sucks. I would be disappointed also. Hopefully yall can make some time soon to get together.
