<human>: I used to have a fairly close relationship with my brother [23] but that all changed once he got married. Long story short, there's a ton of tension between him and his wife and the rest of the family. I try my best to stay on their good side, but I don't feel like I know my brother at all anymore. They have a one-year-old daughter, whom I adore.

Recently, my SIL got a job, requiring childcare for the first time. I volunteered to do it for free for a few months, giving them time to find someone long-term they could afford. I've been watching my niece three days a week for a few weeks now, and things seem to be going great.

They initially told me not to take any books off the top shelf so the baby doesn't tear them. Well, the other day, I noticed that among those top shelf books was a verrry small camera. I don't know how to tell if it was recording sound, which is definitely illegal. I suppose I should assume it wasn't. It was hooked up to the DVR.

I feel frustrated and embarrassed (I mean, I know I've picked my nose at some point, and a wedgie or two), but should I just shrug it off? I don't have a good relationship with them anyway, and I want to be able to see my niece. Is their recording me understandable from the eyes of others, or is it a breach of trust? Should I try to talk to them about it, or just let it all go?

Give me a shortened version of the text
<bot>: I watch my niece a few days a week and discovered a nanny cam the other day. Am I justified in feeling irritated?
