Not Talking at Daycare?

So since E is talking so much and often won't be quiet.  I find it amusing that he won't talk at daycare.  His teachers haven't heard him say a word!  Weird.  Huh? But, I'm thinking that it's because he just moved up to the two year old room.  All the other kids are practically three years old, and really talk.  E probably just can't get a word in otherwise.  Right?  Well, that's what I'm going to think.  He'll start talking to them when he trusts them.  Then they won't be able to get him to be quiet!
