[Aizawa had expected that to be the reaction. He doesn't even try to grip down on the papers as they're taken away from him. There's a sigh, almost like a petulant teenager, as he listens to the start of an explanation that could probably go on for several minutes. As much respect as he held for the hero, All Might (and a slowly growing respect for Toshinori) that was always going to be something to disagree about. The interruption is welcome, even if it's about his own behavior.]

Hm? [Oh. Right. The casual invasion of privacy.] I did, but never mind that. [He says, as if this were some issue of him borrowing a book without asking instead of looking into someone's personal effects.]

I only skimmed them, [and now he's blatantly admitting to reading the fanmail] but some of those were expressing a lot more than gratitude. [He figured it wasn't something All Might had ever encouraged. He's reasonable enough to assume that; to know that no fangirl sending a letter had any shot in hell of having her feelings returned. Still, the fact they were kept got under his skin like some irritating parasite.]
