<Snipped quote by Emeth>

I am guessing it would be a general thing not to use the gifts on anyone without permission, mostly because it could become awkward quickly and such characters can find themselves ostracised from the student body due to paranoia. I imagine there is a stigma around certain gifts, and those that invade privacy would be big contenders.

Right, but with the gifts that you can't even tell if they're being used or not, there's an extra layer of paranoia. Also, if there's some kind of competition between the houses, I feel like inter-house mind-reading is definitely a thing that's going to happen, but mind-reading within your own "tribe" might be a personal taboo for some.
