As I mentioned here, Little Miss had a sleepover at the In-Laws' apartment. When I picked her up the next morning, I asked how her weekend went. She looked at me and said she had fun, but "Well, you won't be happy with some of it."
As it turns out, she gets spoiled at her grandparents' house and things aren't done the same way they are done at home which is expected - one wants grandparents to spoil because many, many children don't have grandparents these days. One day (and soon, I imagine), she'll start to keep secrets from me so I try to react calmly so she'll share information with me as long as possible. In the meantime, I'm going to glory in the fact that she's still honest with me.
