I feel like if you have the impulse to read during social situations, you should be more choosy about what events you're attending. I think it's generally acceptable to check something on your phone or send a quick text at a party, etc., but I don't see people just scrolling on their phones all night. I'd think the same thing about them, if I did, that they should've just stayed home.

Edit: I'm talking about social events you're willingly choosing to attend, btw, not, like, family stuff that is boring or unpleasant but feels obligatory. I think it's totally normal to escape into your phone at things you don't want to attend but feel like you need to. I have the Kindle app on my phone, so it's easy to read in those situations.
