hold off/worth it

hold off  延期する･先送りする wait to do something

I'm just calling to check that you're still coming to fix my roof tomorrow.

  That's the plan. As long as the rain holds off.

That's why I called. I just saw on the news that there's a chance we'll get some rain. Is it worth me taking the day off work if you might not be able to come?

Well, it's up to you, of course, but the chances of it staying fine are pretty good.

  Okay. Thanks.

worth ｩヮ-ｽ adj)価値がある、値打がある
