Ok, another scenario, by mistake she leaves a laptop logged into her email and social media, messenger etc, do you look through it? In general it feels wrong to me, I certainly wouldn't appreciate if she went through my shit. Of course circumstances differ so the answer may be different depending. Just two days ago, my brother and his son were sleeping over at my place, both were a bit drunk and my brother went to sleep. My nephew said to me, psst, I figured out my dad's laptop password, let's look at what he was arguing about with this bitch (family drama involving my nephew somewhat). I said no fucking way, don't look at your dad's private shit. I didn't want drama so I didn't raise a more of stink right there but told my brother later.
