I'm not sure

Alternative: "I don't know"

In conversation, when the person speaking to you wants you to feel like you're part of the conversation, but doesn't want to give you an opening. This conveniently allows the speaker to continue to ramble on about something trivial while the other person can only stand there and take it.

I'm sure they'll continue World Youth Day

1. An expression of support for an effort, organization or person. Often comes after a list of achievements.

2. A paraphrase of Patrick Baron's hopes for Pope Benedict XVI upon the naming of the pontiff on April 20, 2005.

"Radiohead is totally turning the tables on the music industry. They're letting people set their own price for the new album, even giving it away for free. And I'm sure they'll continue World Youth Day!"

“It means that he’ll continue the great work of Pope John Paul! I’m sure he’ll continue World Youth Day! And … he’s just an awesome holy man!”
