Philosophy isn't really the topic for this, but oh well.

Here is an Interesting Question me and my friend came up with:
If everyone in the world had the power to know one thing about people they were in the presence of, like their favourite food, what they were currently thinking, or their bank account details, what would be your thing?

If you want to answer the question, please do so before reading any of the replies, and also say why you'd pick that thing.

Their opinion about me. I bet most people see me as an ugly childish man whom they don't want to interact with. So, if I know what they think about me, I can avoid them first rather than interact with them who may show their polite sides and being nice despite deep in their heart they just want their interaction with me is over as soon as possible.
