go over (something)

"Going over" something means discussing or reviewing it.

You can "go over" things like:

• plans
• lists of rules
• someone's work

You can "go over" things that have already been done or discussed. You can also "go over" things that are new. For example, say this to someone who's going to participate in your wedding ceremony:

Let's go over what you're supposed to do on the day of the ceremony.

Why don't we (do something)

This is a way to make a suggestion to do something together. You use this when you expect the listener to agree with you:

I don't feel like cooking tonight. Why don't we order something out?

Why don't we make a deal: if I help you with this, you have to promise to come to my game on Sunday.

(someone's) day-to-day responsibilities

Your "responsibilities" at work are things that you're supposed to do. You can talk about your responsibilities in general:

I'm responsibile for all of the company's hiring decisions.

But you can also talk about "day-to-day" responsibilities. These are small tasks that you do each day:

Your day-to-day responsibilities will include things like answering customer emails, scheduling travel arrangements for the sales team, preparing for team meetings, and things like that.
