Everybody was new.

I ran across a few people, and one just the last time I played who told us in the middle of a dungeon that he was new. I simply replied that I wish he would have told us earlier so we could have gave him the run-down of the dungeon. He told me that he was afraid to say it because the last couple times he did everybody in the dungeon left.

I just want to say please don't be afraid or let those types of people make you shy away from telling the group that you're new. It'll save everyone some time to give you a heads up on what to expect.
