"Not quite. There was wind, and the key got caught on her finger once, and it was all very plausibly deniable until it wasn't."
"The wind I was counting as part of the weird telekinesis, and the key getting caught – yeah, plausibly deniable until not."
"So… ability to, at the least, do some telekinesis and wind manipulation, with the constraint that it all has to be plausibly deniable or else I forget about it?"
"Do you have any friends you talk to fairly often? Perhaps daily? Or weekly? Bonus points if they're likely to call you at any point during the day."
"… I have a bunch I speak to relatively frequently, and then 'has a chance of calling me out of the blue' stretches to– like, half the school?"
"Try to do the thing you did to the key and the pen, but this time to the event 'someone will call you.' Make it general, to start."

It's a pretty short conversation.
