A: Are you ready to go? The movie will begin in 40 minutes.

B: Sorry, but I need to come to grips with this new software update first.

Note: “Grip” refers to the act of grabbing something and keeping a firm hold of it. This idiom can be best explained by using two wrestlers as an example. First they stand toe to toe facing each other and size each other up. Then they do a little pushing at each other. Then they begin to shove at each other. Then, all of the sudden, they grab each other by the arm and the fight begins. So “coming or getting to grips” is synonymous with “starting to deal with someone or something difficult or challenging in a sensible way.”
