There you go.

You say "There you go" when you're giving or handing a person something:

A: Can you pass me a napkin?

B: There you go.

More generally, you use it when you're doing something for another person. For example, say "There you go" when:

• you stand up to let someone sit down
• you've finished tying someone's necktie for them
• you clear a space on the kitchen counter for someone to set a hot dish on

You can also say "Here you go" in the same way. There are no absolute rules for when to use one or the other, but I would use "Here you go" if I brought something to them from far away, and "there you go" if I'm sitting in one place and handing them the object.

(something) should be (adjective)

Sometimes people talk about their guesses with "should". Use "should" to talk about something that you strongly think is true, but you're not completely sure of:

They should be there at the airport to meet us.

This should be pretty easy.

If we all pitch in and help out, it shouldn't take too long.

(something) is up and running

Use this expression to talk about things that are now working and ready to use. Here are some things that you can describe as "up and running":

• a computer
• a website
• a factory
• a new government program

In the example above, the speaker says "You should be up and running." However, what he means is:

The software should be up and running now.

"You should be..." sounds more casual and friendly.
