“I want to check out the new café, but there’s a music festival this weekend and I don’t think I have time to do both.”

“Let’s go to the music festival. We can always go to the café later.”

“Can always” is a phrase we use when considering our options. We often use it to say a backup option or escape route in case a plan goes badly. For example, you might be interested in reading a certain book, but worried that you will get bored in the middle. You should try reading it anyway, because you can always quit if you get bored with it. You should go to the party; you can always leave if you aren’t having fun.
