Real English Twenty-Two: catch up 

The below is a phone conversation I had the other day.

Mom:  Hey Glenn. How are you doing?
Glenn: Alright, thanks. What's up?
Mom:  I was just a little concerned because recently you haven't updated the blog recently...
Glenn:  I am sorry but give me a break!  As you know, the past month and a half or so have been crazy, so I am behind on the blog...
Mom:  Only the blog?  Are you behind on anything else?
Glenn:  Yeah, a few things.  For example, I really need to catch up on sleep, news, gossip, study...
Mom:  I wouldn't worry too much about it.  You can make up for it later.
Glenn:  Yeah, I know. But I plan to catch up on some of it, especially the blog and sleep, this weekend. 
Mom:  Sounds like a good plan!
Glenn: Oh yeah! I forgot to tell ya.  I got i-phone 5 on Wednesday of this week!  It is my first smart phone.  Everyone always said to me, "You still have a regular cell phone!!  You are so behind the times!!  Get with it!"  So I got up the courage to overcome my fear of gadgets and technology and finally made the big step into the modern world!  So, please, give me some credit! I finally caught up with the times!!
Mom:  That's great news! See you in Facetime!
