Today was Olivia's first day at her new ballet class - she enjoyed it fine, no problem with switching teachers or meeting new kids or anything like that. She's very different from Sarah in that respect. At 3, Sarah would have spent the entire half hour hiding behind a chair in the corner of the room. In fact, as Lana pointed out, she might still. At least for the first few minutes - she's a lot more tentative in new situations.
