Like in this TIC situation and you ask for it, would she give it to you?
I mean I don't have my wife's and she doesnt have mine either but if I asked or she asked then we would both freely give it. In fact we are both auto logged into our respective laptops that we use interchangeably so we can freely access each others stuff all the time without asking if we wanted.
IMHO there's a difference between not having it and actively denying it.
